Key Features

The LT1175CS8#TRPBF is a negative micropower regulator designed by Analog Devices to deliver up to 500 mA output with low dropout. It offers excellent efficiency due to its quiescent current of just 45 µA during normal operation and only 10 µA in shutdown. Unlike typical regulators, this model supports user-selectable current limits for flexible design integration. Furthermore, its wide input range up to -20 V enables broad use across various power platforms. The regulator tolerates reverse output voltages. Prevents damage during reverse conditions. Its compact SOIC package supports integration in dense circuit layouts, while its loop stability allows use with many types of capacitors.

Applications

Powering analog sensors and amplifiers in medical and industrial monitors
Supplying modems and DSP circuits in telecom infrastructure
Driving A/D and D/A converters in high-resolution audio equipment
Controlling voltage rails in instrumentation with tight power constraints
Managing battery-backed memory systems in portable data terminals

Product Overview

Analog Devices’ LT1175CS8#TRPBF is built to regulate negative voltages with minimal power loss. It operates efficiently, even under low voltage drops, making it suitable for portable electronics. Its shutdown feature helps reduce system power when needed, while internal current limit options provide added flexibility. Because of its reverse output protection, the regulator offers greater reliability during power transients. It works well across a wide range of temperatures and fits easily into small enclosures thanks to its narrow SOIC package. Designed for engineers who need performance, safety, and space savings. The LT1175CS8#TRPBF is a practical solution for negative voltage rails.
