LR9280中文资料150mA LDO REGULATOR数据手册UTC规格书

描述 Description

The UTC  LR9280 is a typical LDO (linear regulator) with the

特性 Features

of high output voltage accuracy, low supply current, low ON-resistance. Internally, there’re many functions of UTC LR9280which can be seen in the block figure. There are a voltage reference unit, an error amplifier,  resistor-net for voltage setting, a current limit circuit, and a chip enable circuit in each UTC LR9280.The output voltage of these ICs is fixed with high accuracy. B version has a chip enable pin,  therefore ultra-low consumption current standby mode can be realized with the pin.   FEATURES   Standby Mode (TYP=0.1µA)Supply current (TYP=1µA)   (Except the current through CE pull-down circuit)Output voltage accuracy (±2.0%)Output voltage Range (1.2V~3.6V)Dropout voltage (TYP=0.25V )(IOUT=150mA 3.0V Output type)Line regulation (TYP=0.05%/V)Temperature-Drift Coefficient of Output Voltage (TYP=±100ppm/°C)Ceramic capacitors are recommended to be used with this IC (1μF)
