HT7550-1 IC TO-92 5V 100mA LDO VOLTAGE REGULATOR 7550-1 holtek72-18 HT7550-1

Product Overview

A high-efficiency, ultra-low-power positive linear voltage regulator designed to deliver a stable, fixed 5V output using low-dropout (LDO) technology. It features an exceptionally low quiescent current (typically 2.5 µA) and supports a high maximum input operating voltage up to 30V, making it highly optimized for battery-powered systems, standalone electronics, and industrial equipment requiring an efficient, long-lasting power supply line. Operating reliably across a temperature range of -40°C to +85°C, the device can provide up to 150mA of continuous output current within a compact through-hole footprint.
