LT1761ES5-BYP#TRMPBF

High PSRR, Low Noise Linear Regulator with Bypass Pin for Precision Power Rails

Product Description

Product Overview

The LT1761ES5-BYP#TRMPBF is a high-performance low dropout (LDO) linear regulator providing a fixed 5.0 V output with ultra-low noise and high power-supply rejection ratio (PSRR). Featuring an external BYP bypass pin, this device significantly reduces output noise and improves transient response, making it ideal for powering sensitive analog circuitry, precision data converters, RF front ends, and other noise-critical power rails. It operates with a low dropout voltage and maintains stability with small low-ESR output capacitors.
