Key Features: • 1% output voltage tolerance • 0.01%/V line regulation • 0.3% load regulation • Min. 1.5A output current • Available in hermetic TO-220 The SG117A Series are 3-terminal positive adjustable voltage regulators which offer improved performance over the original 117 design. A major feature of the SG117A is reference voltage tolerance guaranteed within ± 1%, allowing an overall power supply tolerance to be better than 3% using inexpensive 1% resistors. Line and load regulation performance has been improved as well. Additionally, the SG117A reference voltage is guaranteed not to exceed 2% when operating over the full load, line and power dissipation conditions. The SG117A adjustable regulators offer an improved solution for all positive voltage regulator requirements with load currents up to 1.5A.

Key Features: • 8V to 40V operation • 5V reference • Reference line and load regulation of 0.4% • Reference temperature coefficient < ± 1% • 100Hz to 300KHz oscillator range • Excellent external sync capability • Dual 50mA output transistors • Current limit circuitry • Complete PWM power control circuitry • Single ended or push-pull outputs • Total supply current less than 10mA This monolithic integrated circuit contains all the control circuitry for a regulating power supply inverter or switching regulator. Included in a 16-pin dual-in-line package is the voltage reference, error amplifier, oscillator, pulse width modulator, pulse steering flip-flop, dual alternating output switches and current limiting and shut-down circuitry. This device can be used for switching regulators of either polarity, transformer coupled DC to DC converters, transformerless voltage doublers and polarity converters, as well as other power applications. The SG1524 is specified for operation over the full military ambient temperature range of -55°C to +125°C, the SG2524 for -25°C to +85°C, and the SG3524 is designed for commercial applications of 0°C to +70°C.

Key Features: • Source or sink 5A peak • Half-bridge with internal diodes • TTL input compatibility • Either dual- or tri-state output • Direct PWM motor drive from microprocessor • Built-in thermal protection • SG3635P replaces UDN2935Z The SG1635 is a monolithic integrated circuit designed to interface low-level logic signals with high-current, inductive, or capacitive loads. This device is particularly adept at high-speed pulse width modulation for motor drives or Class D audio amplifiers, and when used in pairs, they can provide full bridge drive for bi-directional control. With TTL-compatible units, this device will either source or sink up to 5A of peak current with interlock protection to insure that source and sink cannot be on simultaneously. Additional protection is provided by thermal shutdown of the source output if the chip temperature rises above 160°C. High speed internal commutating diodes are also included.

Key Features: • Seven npn Darlington pairs • -55°C to 125°C ambient operating temperature range • Collector currents to 600mA • Output voltages from 50V to 95V • Internal clamping diodes for inductive loads • DTL, TTL, PMOS, or CMOS compatible inputs • Hermetic ceramic package The SG2000 series integrates seven NPN Darlington pairs with internal suppression diodes to drive lamps, relays, and solenoids in many military, aerospace, and industrial applications that require severe environments. All units feature open collector outputs with greater than 50V breakdown voltages combined with 500mA current carrying capabilities. Five different input configurations provide optimized designs for interfacing with DTL, TTL, PMOS, or CMOS drive signals. These devices are designed to operate from -55°C to 125°C ambient temperature in a 16 pin dual in line ceramic (J) package and 20 pin Leadless Chip Carrier (LCC). The plastic dual in–line (N) is designed to operate over the commercial temperature range of 0C to 70°C.

Key Features: • 2% Internally Trimmed Output • Two regulated outputs • Output current in excess of 1000mA • Low quiescent current standby regulator • Input-output differential less than 0.6V at 0.5A • Reverse battery protection • 60V load dump protection • -50V reverse transient protection • Short circuit protection • Internal thermal overload protec-tion • Available in plastic TO-220 • ON/OFF switch for high current output The SG29125/125A is a dual 12V/5V positive voltage regulator. One output is a high current (up to 1000 mA) regulator that can be turned on or off by a high impedance low current TTL compatible switch. The second or standby output remains on regardless. The on/off switch not only shuts off the high current output but actually puts the IC in a micropower mode making possible a low quiescent current. This unique characteristic coupled with an extremely low dropout, (.55V for output current of 10mA) makes the SG29125/125A well suited for power systems that require standby memory. The SG29125/125A includes other features which were originally designed for automotive applications. These include protection from reverse battery installations and double battery jumps. The high current regulator has overvoltage shutdown to protect both the internal circuitry and the load during line transients, such as load dump (60V). In addition, the high current regulator design also has built-in protection for short circuit and thermal overload. During these fault conditions of the primary regulator the standby regulator will continue to power its load. The SG29125 is the 12 volt, ±5% version of a family of dual regulators with a standby output voltage of 5V. Other high current outputs of 5 and 8.2 volts are available. Also available is the SG29125A which offers an improved output voltage tolerance of ±2%. They are available in the plastic TO-220 power package and are designed to function over the automotive ambient temperature range of -40C to 85C.

Key Features: • 300mA output current capability • High-voltage output • No output latch-up at 20V • High speed switching • TTL or DTL compatible diode-clamped inputs • Standard supply voltages The SG5541B/SG55461/SG55471 (SG75451B/SG75461/SG75471) series of dual peripheral Positive-AND drivers are a family of versatile devices designed for use in systems that employ TTL or DTL logic. This family of drivers are direct replacements for the Texas Instruments SN55451B/61/71 (SN75451B/61/71)series. Diode-clamped inputs simplify circuit design. Typical applications include high-speed logic buffers, power drivers, relay drivers, MOS drivers, line drivers, and memory drivers. The SG55451B/SG55461/SG55471 drivers are characterized for operation over the full military ambient temperature range of -55°C to 125°C and the SG75451B/SG75461/SG75471 drivers are chracterized for operation from 0°C to 70°C.
