DESCRIPTION
The SAT127 is a military qualified, wide-input range linear regulator designed for harsh
environments. Packaged in a hermetic, 8-Pin package, this device is an excellent choice
for applications with limited board space. The SAT127 provides ±1.0A of output current
over the full Mil-Temp range of –55oC to +125 oC . The device also features internal
thermal shutdown, output current-limiting circuitry and ±1% output accuracy. The
SAT127 is provided in adjustable and fixed output voltage configurations. The
adjustable only requires 2 external resistors per output to program output voltages. Fixed
versions do not require any additional components saving cost and board space.
