G918 台湾致新代理商 GMT LDO系列单电源LDO

GeneralDescription
The G918 series is a low supply current, high PSRR, low noise, and low dropout linear regulator that comes in a space saving SOT-23-5 package. The supply current at no-load is 100μA. In the shutdown mode, the maximum supply current is less than 1μA. Operat-ing voltage range is from 2.5V to 6.0V. The over-current protection limit is set at 750mA typical. An over-temperature protection circuit is built-in in the Device to prevent thermal overload. These power saving features make the G918 series ideal for use in the battery-powered applications such as notebook computers, cellular phones, and PDA’s.

The G918 has one modes of operation. When an output other than the preset value is needed, two external re-sistors should be used as a voltage divider. The output voltage is then adjusted by the resistor ratio.
