NCP4587: Linear Voltage Regulator, LDO, 150 mA, with Auto Low Power Mode

Product Description
The NCP4587 is a CMOS 150mA LDO which switches to a low power mode under light current loads. The device automatically switches back to a fast response mode as the output load increases above 3mA or can be placed in permanent fast mode through a mode select pin. The family is available in a variety of packages: SC70-5 (SC88A), SOT23-5 and an ultra thin (0.4mm) small 1.2x1.2 mm XDFN. Voltage options are available between 0.8V and 4.0V. Voltages can be available in 100mV steps - contact your local sales office to request your required package, voltage output and discharge combinations.
Features   Benefits
     
  • Iq is 55uA (typical) or 1.5uA in LP mode
 
  • Automatically switches to LP mode to save power and battery life
  • Good PSRR - 70dB typical
 
  • Excellent noise rejection and filtering in Fast Mode
  • Very Low Dropout: 120 mV when Vo > 2.6V
 
  • Low Input Voltages accepted, extending battery life and reducing power dissipation
  • Auto Discharge, Enable high versions available
 
  • Choose between fast shutoff or fast restart of the output voltage
  • Excellent Output Voltage accuracy: ±1%
   
Applications   End Products
  • Battery powered applications
  • Applications which are usually ON but not driving loads
 
  • Blue Ray, STB, DVD players
  • Instrumentation, meters, cameras
