LT1761ES5-1.2#TRPBF

The LT1761ES5-1.2#TRPBF is a fixed 1.2 V output, 100 mA low-dropout linear regulator (LDO) from Analog Devices, purpose-built for noise-sensitive applications that demand minimal power consumption. As a member of the LT1761 series, it combines a very low dropout voltage—typically 300 mV at full load—with an ultralow ground current of around 20 µA during operation and less than 1 µA in shutdown. The device delivers exceptionally clean output, with noise performance in the 20 µVRMS range across a 10 Hz to 100 kHz bandwidth, and remains stable with compact, low-ESR ceramic capacitors as small as 1 µF. Housed in a 5‑lead TSOT‑23 package, the regulator integrates current limiting and reverse-battery protection, supporting continuous, reliable regulation in tight board layouts.

This LDO is widely deployed in industrial, medical, and communications systems to provide precision power rails for ADCs, DACs, RF phase-locked loops, and sensitive sensor front-ends. Its micropower profile also suits battery-operated instrumentation and portable wireless modules where extending runtime is critical. From a procurement standpoint, the LT1761ES5-1.2#TRPBF is an active, long-lifecycle product supplied in tape-and-reel format for automated assembly, with a matte tin lead-free finish that satisfies RoHS directives. The “E” grade defines an operating junction temperature range of −40 °C to +125 °C, making the part appropriate for extended industrial environments without the cost overhead of full military qualification. Engineers and supply-chain teams typically source this device through authorized distribution to guarantee traceability, component authenticity, and consistent low-noise performance over production volumes.
