1 Introduction

The TPS7H1121-SEP is a radiation-tolerant, low-dropout linear regulator (LDO) which operates over a wide input voltage range and is optimized for powering devices in a space environment. The device is capable of sourcing up to 2A over a 2.25V to 14V input. It offers excellent stability and features a programmable current limit with a wide adjustment range. To support the complex power requirements of FPGAs, DSPs, and micro-controllers, the TPS7H1121-SEP provides enable on and off functionality, programmable soft start, and a power good open-drain output.

The device is offered in a 24-pin plastic package. General device information and test conditions are listed in Table 1-1. For more detailed technical specifications, user-guides, and application notes please go to TPS7H1121-SEP product page.
