XC6227C381PR-G

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The XC6227C381PR-G is a fixed-output linear voltage regulator from the Torex XC6227 series, providing a nominal output of 3.8V with a maximum continuous load current of 700mA. It operates within an input voltage range up to 6V and maintains a typical dropout voltage of 120mV at full load. The device features a low quiescent current of 100µA and offers high power supply rejection ratio (PSRR) of 65dB at 1kHz. It includes built-in protection mechanisms such as overcurrent protection, thermal shutdown, and reverse polarity protection. The component is housed in a compact SOT-89-5 surface-mount package and is rated for operation across an extended temperature range from -40°C to +85°C.
