G9161 Global Mixed-mode Technology 400mA High PSRR, LDO Regulators General Description The G9161 series is a low supply current, high PSRR, and low dropout linear regulator that comes in a SOT-89, SOT-223, TO-252 and SOP-8 with Power PAD package. The supply current at no-load is 90µA. Operating voltage range 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 Device to prevent thermal overload. Features Low, 90µA No-Load Supply Current Guaranteed 400mA Output Current PSRR=65dB @ 120Hz; 55dB @ 1KHz Over-Temperature Protection and Short-Circuit Protection Output Voltage: 1.20V~5.00V (G9161-XXX) Stable with Low Cost Ceramic Capacitors The output voltage range is from 1.2V to 5.0V.
