XC6221D282GR-G

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

The XC6221D282GR-G is a fixed-output low-dropout (LDO) voltage regulator manufactured by Torex Semiconductor. It provides a stable 2.8 V output with a maximum load current of 200 mA. The device operates within an input voltage range of 1.6 V to 6 V and maintains a typical power supply rejection ratio (PSRR) of 70 dB. Quiescent current is specified at 25 uA, ensuring efficient operation in battery-powered applications. The regulator features a dropout voltage of approximately 95 mV at full load and offers a line regulation of 0.01 %/V. It is housed in a USP-4 surface-mount package and supports an operating temperature range from -40°C to +85°C.
