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 15µA Input stability: typically 0.2%/V Ultra low dropout voltage, 0.1V @ IOUT = 100mA
