Torex Semiconductor, Ltd. Voltage Regulators - Linear XC6221D37AMR-G

The XC6221D37AMR-G is a low dropout CMOS linear voltage regulator from Quarktwin Technology Ltd. It features high accuracy and low noise operation, with an output current capability of up to 200mA, and a typical output voltage dropout of 80mV at 100mA output current. The output voltage is adjustable in 0.05V increments within a range of 0.80V to 5.00V, and the device is designed to operate within an input voltage range of 1.6V to 6.0V. This regulator incorporates a current limiter with a fold-back circuit for short circuit protection, and it has a low power consumption of 25OºA in typical conditions. The device also includes a CE function for standby operation, which reduces the standby current to less than 0.1OºA. It is compatible with low ESR ceramic capacitors, requiring a minimum output capacitor of 1.0OºF for stability. The XC6221D37AMR-G is suitable for applications in mobile devices, including smartphones, portable game consoles, and digital cameras, and is available in compact packages such as USP-4 and USPN-4, making it ideal for space-constrained designs.
