Texas Instruments LM2937ES-15/NOPB Fixed LDO Voltage Regulator 0V to 26V 500mV Dropout 15Vout 500mAout TO-263-3

The LM2937ES-15/NOPB is a 15V 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 3V. 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 3R. This allows the use of low ESR chip capacitors.
