XC6221D122GR-G

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

The XC6221D122GR-G is a fixed-output CMOS low-dropout regulator manufactured by Torex Semiconductor. It provides a stable 1.2 V output with a maximum continuous 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 of 70 dB. Quiescent current is limited to 25 uA, ensuring efficient operation in battery-powered systems. The dropout voltage is specified at 230 mV under full load conditions. Line regulation is rated at 0.01 %/V, while load regulation remains at 10 mV. The component supports surface-mount installation in a USP-4 package and functions reliably across an operating temperature range from -40°C to +85°C.
