Overview
The LX8819 is a dual channel positive-voltage linear regulator. This dual regulator has one fixed output coupled with an adjustable output. Each channel features low dropout and high accuracy. The LX8819 provides designers with a flexible power management solution, minimal printed circuit board area and shorter design cycles. Each channel can supply up to one amp independently with a regulator design optimized for system efficiency by consuming minimal ground current while directing quiescent current to the load. The LX8819 features on-chip trimming of the internal voltage reference enabling precise output voltages, typically ±1% of it’s specified value, while the BiPolar output transistor has a low dropout voltage even at full output current (VDO < 1.25V typical @ 1A). Thermal and Short Circuit Current Protection are integrated on-chip and operate independently for each regulator output. The LX8819 regulator is stable with a low-value output capacitor, typically 2.2µF on the outputs, allowing designers flexibility in external component selection. Microsemi’s S-PAK and D-PAK power packages enable maximum power dissipation and ease of assembly using surface mount technology. Features
