Description

The TPS7H1101-SP is a radiation-hardened LDO linear regulator that uses a PMOS pass element configuration. This device operates over a wide range of input voltage, from 1.5 V to 7 V while offering excellent PSRR. The TPS7H1101-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 TPS7H1101-SP provides enable on and off functionality, programmable SoftStart, current sharing capability, and a PowerGood open-drain output.

The TPS7H1101-SP is available in a thermally-enhanced 16-pin ceramic flatpack package (CFP).
