| GM6353 450mA ULTRA LOW DROPOUT POSITIVE VOLTAGE REGULATOR Description GM6353 series is a group of positive voltage output, three-pin regulators, that provide a high current even when the input/output voltage differential is small. Low power consumption and high accuracy is achieved through CMOS and programmable fuse technologies, with the output voltage range from 1.5V to 6.0V GM6353 consists of a high precision voltage reference, an error correction circuit, and a current limited output driver. Transient response to load variations has been improved in comparison to the existing series. The GM6353 incorporates both over temperature and over current protection. Features Maximum output current up 450mA Output voltage from 1.5V to 6.0V in 0.1V increments Output voltage accuracy : 2% CMOS low power consumption, typically 15A Input stability: typically 0.2%/V Ultra low dropout voltage, 0.1V @ IOUT = 100mA Application Palmtops Portable Cameras Video Recorders Battery Powered Equipment Reference Voltage Sources Typical Application Circuits GM6350-x.x VIN VIN VSS COUT 1F (Tantalum) VOUT CIN 1F (Tantalum) RL www.gammamicro.com.tw 1 GM6353V2.00 GM6353 450mA ULTRA LOW DROPOUT POSITIVE VOLTAGE REGULATOR Marking Information and Pin Configurations (Top View) SOT223 GM6353G VVAYWW 1 GND 2 VOUT 3 VIN G: Green Product VV: Voltage suffix (18 = 1.8V, 50 = 5.0V...)
