Product Overview
NCP500 is a Texas Instruments fixed-output low-dropout linear regulator in the Power_Management category. It is specified as a low-noise LDO regulator with 150 mA maximum output current and a 1.8 to 6.0 V operating input range. The feature list identifies 170 mV dropout voltage, 2.5% output voltage accuracy, 20 us typical enable turn-on time, and 50 uV typical RMS noise over 10 Hz to 100 kHz without a bypass capacitor.
Package options are TSOP-5 case 483 and DFN 2x2.2 mm case 506BA. The device supports a 1.0 uF ceramic output capacitor, and the electrical characteristics use a 1.0 uF input capacitor. Pin functions include Vin for positive supply input, GND for power supply ground, Enable for logic-controlled shutdown or turn-on, and Vout for the regulated output.
Specified output-voltage options include 1.8 V, 1.85 V, 2.5 V, 2.6 V, 2.7 V, 2.8 V, 3.0 V, and 3.3 V typical outputs across stated input, load, and temperature conditions. These facts support use on compact regulated rails where low noise, enable control, and fixed-voltage output selection are required.
