TPS7H1101A-SP 1.5-V to 7-V Input, 3-A, Radiation-Hardened LDO Regulator
PMOS pass element configuration. It operates over
1 Features
a wide range of input voltage, from 1.5 V to 7 V
while offering excellent PSRR. The TPS7H1101A-SP
features a precise and programmable foldback current
limit implementation with a very-wide adjustment
range. To support the complex power requirements of
FPGAs, DSPs, or microcontrollers, the TPS7H1101A-
SP provides enable on and off functionality,
programmable soft start, current sharing capability,
and a Power Good open-drain output.

(3) These units are intended for engineering evaluation only.
They are processed to a noncompliant flow (that is, no
burn-in, and so forth) and are tested to a temperature
rating of 25°C only. These units are not suitable for
qualification, production, radiation testing or flight use. Parts
are not warranted for performance over the full MIL specified
temperature range of –55°C to 125°C or operating life.
