1 GENERAL DESCRIPTION The series arelowdropout linear regulators and optimized to provide a high performance solution for battery power system to delivery low quiescent current. The device offer a new level of cost effective performance in cellular phones, laptop and notebook computers, and other portable devices. can provide output value in the range of 1.0V~3.6V by every 0.1V step. The series are designed to make use of low cost ceramic capacitors which ensure the stability of the output current, and enhance the efficiency in order to prolong the battery life of those portable devices. FEATURES Input voltage : 2.5V~7V Output range: 1.0V~3.6V (customized by every 0.1V step) Output current: IN V OUT =1V Dropout voltage: I OUT =100mA Quiescent current : 2μA Typ. PSRR: 100Hz Recommend capacitor: 1μF APPLICATIONS Reference voltage source Toys Bluetooth, wireless handsets Low Consumption Device Others portable electronics device The regulators are available in SOT 23 packages. Standard products are Pb free and Halogen free. TYPICAL APPLIC PIN ASSIGNMENT SOT 23 Datasheet, 2018 Version 1.2Page1
