NCP4588: Linear Voltage Regulator, LDO, Output Capacitor Free, 200 mA

Product Description
The NCP4588 is a CMOS 200mA LDO which is stable without an output capacitor. This results in a reduction in component count, cost and board area, as well as contributing to a more robust solution in hostile environments. With quiescent current < 9.5 uA and PSRR > 60 dB, the device is an excellent trade off between the two features. The family is available in a variety of packages: SC-70-5 (SC88A), SOT23-5 and a small, ultra thin 1.2 x 1.2 x 0.4 mm XDFN. The device output voltage range is 1.0 to 4.2 V with voltage outputs available in 0.1 V steps - contact you local sales office with your specific output voltage requirement.
Features   Benefits
     
  • Low Iq: 9.5 uA (typical)
 
  • Well suited to low power or battery powered products
  • Good PSRR: 70dB Vo <1.22 to 60dB at Vo >2.2V
 
  • Good rejection of noise or ripple introduced on the input of the regulator
  • Low Dropout: 270 mV typical
 
  • Vin can be close to Vout meaning less power dissipated across the regulator.
  • Auto-discharge feature available
 
  • Pulls output low when the device is disabled ensuring quick switchoff
Applications   End Products
  • Power Supply, POL, filtering
 
  • HDD, STB, DVD players
  • Industrial meters, Smart meters
  • Cameras
