  • NCP145 is a 500 mA LDO equipped with NMOS pass transistor and a separate bias supply voltage (VBIAS). The device provides very stable, accurate output voltage with low noise suitable for space constrained, noise sensitive applications. In order to optimize performance for battery operated portable applications, the NCP145 features low IQ consumption. The XDFN4 1.2 mm x 1.2 mm package is optimized for use in space constrained applications.
  • Features
  • Ultra-Low Dropout of Typ. 140mV - Allows to save power and operates with very low Vin-Vout voltage.
  • Fixed Output Voltage options from 1.0V to 1.8V - Excellent choice for low voltage Vcore applications
  • 140 mV typical dropout at the full 500 mA load. - minimizes the power loss across the regulator
  • Guaranteed Output Current from 0mA to 500mA - Very good choice for high current applications
  • 0.5% Typical Output Voltage Accuracy - Perfect fit for POL applications
  • Output Current in Excess of 500mA
  • Output Active Discharge option available
