G984 Global Mixed-mode Technology Inc. 300mA High PSRR LDO Regulators 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. Low, 90µA No-Load Supply Current Guaranteed 300mA Output Current Maximum Dropout Voltage is 2V @ 300mA Load PSRR=65dB @ 120Hz; 55dB @ 1kHz Over-Temperature Protection and Short-Circuit Protection Fixed Output Voltage: 1.20V Max.
