NCV8537 Linear Regulator - High Accuracy, Low Dropout, Power Good Function 500 mA www.onsemi.com The NCV8537 is a high performance low dropout linear voltage regulator. Based on the popular NCV8535, the device retains all the best features of its predecessor which includes high accuracy, excellent stability, low noise performance and reverse bias protection but now includes a Power Good output signal to enable monitoring of DFN10 DFNW10 the supply system. The device is available with fixed or adjustable CASE 485C CASE 507AM outputs and is packaged in a 10 pin 3x3 mm DFN package.
