Negative Voltage Regulators (non-LDO)

Microsemi's negative-to-negative linear voltage regulators products are fit for military and aerospace applications with temperatures ranging from -55^oC to +125^oC*.
The products can accept negative voltages of up to -37V and can generate output voltages as low as -1.25V, at ongoing maximum currents of up to 1.5A. Both fixed and adjustable output voltage modesl are available.
For a product list sorted by SMD and JAN Number, see the HiRel Integrated Circuits Catalog.
*the SG237 and SG237A support 0 to 100^oC temperature range.

Packaging options:
G: TO-257 3-pin Metal Case w/mounting tab, non-insulated
IG: TO-257 3-pin Metal Case w/mounting tab, insulated
K: TO-3, High Current Metal Can, 3-pin
L: Ceramic LCC (Leadless Chip Carrier), 20-pin
R: TO-66, Medium Current Metal Can, 3 or 5-pin
T: Low Current Metal Can, TO-39 (3-pin) or TO-99 (8-pin)

The 8 suffix indicates compliance with the MIL-STD-883, paragraph 1.2.1 compliance, the D suffix indicates compliance with the DESC relevant space standard and the J suffix indicates MIL-M-38510 (JAN) listing.
