G9815 Global Mixed-mode Technology 1.5A High PSRR, Low Noise, LDO Regulators Features General Description The G9815 series is a low supply current, high PSRR, low noise, and low dropout linear regulator making them ideal for battery applications. It is available in TO-252, SOT-223 packages. The supply current at no-load is 45µA. An over-temperature protection circuit is built-in in the Device to prevent thermal overload. And the G9815 is equipped with a short-circuit current fold-back protection circuit to prevent from failure. The G9815 is stable with an output capacitance of 4.7µF or greater Low, 45µA No-Load Supply Current Guaranteed 1.5A Output Current Low Dropout Voltage PSRR=70dB (f=100Hz 1.2V output) Over-Temperature Protection Short-Circuit Protection with Current Fold-back Stable with Low Cost Ceramic Capacitors Low Temperature Coefficient Applications Instrumentation Portable Electronics Wireless Devices PC Peripherals Battery Powered Widgets Ordering Information ORDER NUMBER MARKING VOLTAGE TEMP.
