Global Mixed-mode Technology Inc. G924 300mA Low-Noise LDO Regulators Features Low, 90µA No-Load Supply Current Guaranteed 300mA Output Current Dropout Voltage is 200mV @ 150mA Load PSRR=53dB @ 1kHz Over-Temperature Protection and Short-Circuit Protection Max. Supply Current in Shutdown Mode < 1µA Low Output Noise at 28µVRMS Stable with low cost ceramic capacitors Output voltage: 1.20V~5.00V General Description The G924 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 G924 is from 2.5V to 5.5V. The over-current protection limit is set at 550mA typical and 400mA minimum. An over-temperature protection circuit is built-in in the G924 to prevent thermal overload. These power saving features make the G924 ideal for use in the batterypowered applications such as notebook computers, cellular phones, and PDA’s.
