TEXAS INSTRUMENTS  LM2937IMP-2.5  固定电压稳压器, LDO, 0V至26V, 500mV压差, 2.5V输出, 500mA输出, SOT-223-3

The is a 2.5V fixed output low-dropout LDO Linear Regulator capable of supplying up to 500mA of load current. The use of a PNP power transistor provides a low-dropout LDO voltage characteristic. With a load current of 500mA the minimum input to output voltage differential required for the output to remain in regulation is typically 0.5V. Special circuitry has been incorporated to minimize the quiescent current to typically only 10mA with a full 500mA load current when the input to output voltage differential is greater than 5V. The device requires an output bypass capacitor for stability. As with most low-dropout LDO regulators, the ESR of this capacitor remains a critical design parameter, but the device includes special compensation circuitry that relaxes ESR requirements. The device is stable for all ESR below 5R. This allows the use of low ESR chip capacitors.
