G914Df 300mA低噪声LDO稳压器 致新代理商

　　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 protection 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.
