Torex Semiconductor, Ltd. Voltage Regulators - Linear XC6221A18A7R-G

The XC6221A18A7R-G is a low dropout CMOS linear voltage regulator from Quarktwin Technology Ltd. It features high accuracy, low noise, and high ripple rejection, making it suitable for various applications including mobile devices and digital audio equipment. The output voltage is adjustable in 0.05V increments within a range of 0.80V to 5.00V, with a typical output current of 200mA and a maximum of 250mA. The dropout voltage is specified at 80mV for an output of 3.0V at 100mA. The device operates over an input voltage range of 1.6V to 6.0V and consumes only 25OºA of quiescent current, with a standby current of less than 0.1OºA. It is available in compact packages such as USP-4 and USPN-4, allowing for space-efficient designs. The XC6221 series also includes features like a current limiter for short circuit protection and compatibility with low ESR ceramic capacitors.
