XC6222B371ER-G

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

The XC6222B371ER-G is a fixed-output low-dropout (LDO) voltage regulator manufactured by Torex Semiconductor. It provides a stable 3.7 V output with a maximum continuous current of 700 mA. The device operates within an input voltage range of 1.7 V to 6 V and maintains a typical dropout voltage of 120 mV at full load. Key electrical specifications include a quiescent current of 100 µA, a power supply rejection ratio (PSRR) of 65 dB, and a line regulation of 0.01 %/V. The unit features a voltage accuracy of 1% and is housed in a USP-6C-6 surface-mount package.
