XC6222B39BER-G

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

The XC6222B39BER-G is a fixed-output low-dropout (LDO) voltage regulator manufactured by Torex Semiconductor. It provides a fixed output voltage of 3.95 V with a maximum continuous output 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 0.2 V at 300 mA load. Key electrical specifications include a quiescent current of 100 uA, a line regulation of 0.01 %/V, and a typical power supply rejection ratio (PSRR) of 65 dB. The unit is housed in a USP-6C-6 surface-mount package and supports operation from -40°C to +85°C.
