G914AF中文资料300mA High PSRR, Low-Noise LDO Regulators数据手册GMT规格书

描述 Description

General Description
The G914X is a low supply current, high PSRR low dropout linear regulator that comes in a space saving SOT-23-5 package. The supply current at no-load is 55µA. In the shutdown mode, the maximum supply current is less than 1µA. Operating voltage range of the G914X is from 2.5V to 5.5V. The over-current pro
tection limit is set at 500mA typical and 400mA minimum. An over- temperature protection circuit is built-in in the G914X to prevent thermal overload. These power saving features make the G914X ideal for use in the battery-powered applications such as notebook computers, cellular phones, and PDA’s.
