Torex Semiconductor, Ltd. Voltage Regulators - Linear XC6221B122GR-G

The XC6221B122GR-G is a low dropout CMOS voltage regulator from Quarktwin Technology Ltd., designed for high accuracy and low noise applications. It supports an output voltage range of 1.20V to 5.00V, selectable in 0.05V increments, with a typical output current of 200mA and a maximum of 250mA. The device features a low dropout voltage of 80mV at 100mA output current and operates within an input voltage range of 1.6V to 6.0V. This regulator includes a current limiter with a fold-back circuit for short circuit protection, and it has a low power consumption of 25OºA in typical operation, with a standby current of less than 0.1OºA. The XC6221B122GR-G is compatible with low ESR ceramic capacitors, requiring a minimum output capacitor of 1.0OºF for stability. It is available in compact packages such as USP-4 and USPN-4, making it suitable for space-constrained applications like smartphones, portable game consoles, and digital cameras. The device is also compliant with EU RoHS standards, ensuring it is environmentally friendly.
