  • NCP139 is a 1 A 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 NCP139 features low IQ consumption. The WLCSP6 1.2 mm x 0.8 mm package is optimized for use in space constrained applications.
  • Features
  • Ultra-Low Dropout of Typ. 40mV - Allows to save power and operates with very low Vin-Vout voltage.
  • Adjustable Voltage version - Excellent choice for low voltage Vcore applications
  • 50 mV typical dropout at the full 1 A load. - minimizes the power loss across the regulator
  • Guaranteed Output Current from 0 to 1 A - Very good choice for high current applications
  • 0.5% Typical Output Voltage Accuracy - Perfect fit for POL applications
  • Output Current in Excess of 1 A
  • Output Active Discharge option available
  • Applications
