Torex Semiconductor, Ltd. Voltage Regulators - Linear XC6221B48AMR-G

The XC6221B48AMR-G is a low dropout CMOS linear voltage regulator from Quarktwin Technology Ltd. It features high accuracy, low noise, and a maximum output current of 200mA, with typical performance up to 250mA. The output voltage is adjustable in 0.05V increments within a range of 0.80V to 5.00V, and it maintains a low dropout voltage of 80mV at 100mA output current. The device operates over an input voltage range of 1.6V to 6.0V and consumes only 25OºA of quiescent current, making it suitable for battery-powered applications. The XC6221B48AMR-G includes a built-in current limiter for short circuit protection and features an auto-discharge function for quick output stabilization during standby mode. It is compatible with low ESR ceramic capacitors, requiring a minimum output capacitor of 1.0OºF. The device is available in compact packages such as USP-4 and USPN-4, making it ideal for space-constrained designs in mobile devices, digital cameras, and other portable electronics. The operating temperature range is from -40°C to 85°C, and the product is compliant with EU RoHS standards.
