3 Description

The TPS7H1101A-SP is an improved version of

the TPS7H1101-SP allowing the use of the enable

feature across the entire input voltage range. It is a

radiation-hardened LDO linear regulator that uses a

PMOS pass element configuration. It operates over

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 TPS7H1101ASP

provides enable on and off functionality,

programmable soft start, current sharing capability,

and a Power Good open-drain output.
