NCP146

NCP146 Voltage Regulator - CMOS Low Dropout 300 mA The NCP146 is 300 mA LDO that provides the engineer with a very stable, accurate voltage with low noise suitable for space constrained, noise sensitive applications. In order to optimize performance for battery operated portable applications, the NCP146 employs the dynamic quiescent current adjustment for very low IQ consumption at no−load. Features Operating Input Voltage Range: 1.7 V to 5.5 V Available in Fixed Voltage Options: 1.8 V Very Low Quiescent Current of Typ. 50 mA Low Dropout: 280 mV Typical at 300 mA ±1% Accuracy at Room Temperature High Power Supply Ripple Rejection: 75 dB at 1 kHz Thermal Shutdown and Current Limit Protections Stable with a 1 mF Ceramic Output Capacitor Available in SOIC−8 Package These Devices are Pb−Free, Halogen Free/BFR Free and are RoHS Compliant Typical Applicaitons Home Automation, Factory Automation Portable Medical Equipment Other Battery Powered Applications VIN CIN IN OUT NCP146 GND VOUT COUT 1 mF Ceramic www.onsemi.com 8 1 A L Y W G SOIC−8 CASE 751 MARKING DIAGRAM 8 PC180 ALYW G 1 = Assembly Location = Wafer Lot = Year = Work Week = Pb−Free Package PIN CONNECTIONS OUT GND GND N/C 18 27 36 45 SOIC−8 (Top View) IN GND GND N/C ORDERING INFORMATION See detailed ordering, marking and shipping information on page 8 of this data sheet.
