NCP151 LDO Regulator - Dual, High PSRR 300 mA The NCP151 is a dual linear regulator capable of supplying 300 mA www.onsemi.com output current from 1.7 V input voltage. The device provides wide output voltage range from 0.8 V up to 3.6 V. In order to optimize performance for battery operated portable applications, the NCP151 employs the dynamic quiescent current adjustment for very low I Q consumption at noload. 1 Features XDFN4 Operating Input Voltage Range 1.7 V to 5.5 V CASE 711AJ Available in Fixed Voltage Option: 0.8 V to 3.6 V 2% Accuracy Over Load/Temperature MARKING DIAGRAM Low Quiescent Current Typ. 100 A Low Dropout: 210 mV for 300 mA 2.8 V XX M Low Dropout: 370 mV for 300 mA 1.8 V 1 High PSRR: Typ. 70 dB at 1 kHz OUT1, OUT2 XX = Specific Device Code Stable with a 1 F Small Case Size Ceramic Capacitors M = Date Code Available in XDFN4, 1 mm 1 mm 0.4 mm These Devices are PbFree, Halogen Free/BFR Free and are RoHS PIN CONNECTIONS Compliant IN OUT2 Typical Applications 43 PDAs, Mobile Phones, GPS, Smartphones EPAD Wireless Handsets, Wireless LAN Devices, Bluetooth , Zigbee Bitcoin Miners 12 Portable Medical Equipment OUT1 GND Other Battery Powered Equipment (Top View) NCP151 V IN1 ORDERING INFORMATION IN V OUT2 OUT2 V See detailed ordering and shipping information on page 2 of OUT1 OUT1 this data sheet.
