G913 Global Mixed-mode Technology Inc. 300mA Low-Dropout Linear Regulators Features General Description The G913 is a low supply current, low dropout linear regulator that comes in a space saving SOT-23-5 package. The supply current at no-load is 90µA. In the shutdown mode, the maximum supply current is less than 1µA. Operating voltage range of the G913 is from 2.5V to 5.5V. The over-current protection limit is set at 550mA typical. An over-temperature protection circuit is built-in in the G913 to prevent thermal overload. These power saving features make the G913 ideal for use in the battery-powered applications such as notebook computers, cellular phones, and PDA’s. Low, 90µA No-Load Supply Current Guaranteed 300mA Output Current Dropout Voltage is 200mV @ 150mA Load Over-Temperature Protection and Short-Circuit Protection Two Modes of Operation ---Fixed Mode: 1.5V~4.7V (interval =100mV) 2.84V (G913A), 3.15V (G913B), 4.75V (G913E), Adjustable Mode: from 1.25V to 5.5V Max. Supply Current in Shutdown Mode < 1µA Low Output Noise at 220µVRMS Stable with low cost ceramic capacitors The G913 has two modes of operation. When the SET pin is connected to ground, its output is a pre-set value: 1.5V~4.7V (interval =100mV), 2.84V, 3.15V, and 4.75V. 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 G913 comes in a space saving SOT-23-5 package.
