G923 General Description
The G923 is a low supply current, high PSRR, and low dropout linear regulator that comes in a space saving SOT-23-5 package. The supply current at no-load is 90A. In the shutdown mode, the maximum supply current is less than 1A. Operating voltage range of the G923 is from 2.50V to 5.50V. The over-current protection limit is set at 550mA typical. An over- temperature protection circuit is built-in in the G923 to prevent thermal overload. These power saving features make the G923 ideal for use in the battery-powered applications such as notebook computers,cellular phones, and PDA's.
The G923 has two modes of operation. When the SET pin is connected to ground, its output is a pre-set value: 1.50V~5.00V. There is no external component needed to decide the output voltage. When an output other than the preset value is needed, two external resistors should be used as a voltage divider. The output voltage is then decided by the resistor ratio. The G923 comes in a space saving SOT-23-5 package.
