Features
General Description
„
The G984 series is a low supply current, high PSRR,
and low dropout linear regulator that comes in a space
saving SOT-23-6 package. The supply current at
no-load is 90µA. In the shutdown mode, the maximum
supply current is less than 1µA. Operating voltage
range is from 2.5V to 6.0V. The over-current protection
limit is set at 550mA typical. An over- temperature
protection circuit is built-in in the Device to prevent
thermal overload. These power saving features make
the G984 series ideal for use in the battery-powered
applications such as notebook computers, cellular
phones, and PDA’s.
