Analog Devices LT1761ES5-SD#PBF Integrated Circuits (ICs) Overview
The LT1761ES5-SD#PBF from Analog Devices is an adjustable, micropower low-dropout linear regulator designed to supply up to 100 mA. It supports a wide 1.8 V to 20 V input range and uses an external resistor divider to set the output from 1.22 V up to 20 V, subject to input-voltage and dropout requirements.
With only 20 µA typical quiescent current and less than 0.1 µA shutdown current, the regulator is particularly suitable for battery-powered and always-on electronic systems. It is supplied in a compact 5-lead TSOT-23 package and operates over a junction-temperature range of −40°C to +125°C. The #PBF suffix identifies the lead-free version.
