LR2915中文资料1.5A, LOW DROPOUT REGULATOR数据手册UTC规格书

描述 Description

The UTC LR2915 is CMOS-based positive voltage and a verylow dropout regulator IC that minimum input voltage is 2.5V and iscapable of delivering the continuous output load current up to 1.5A.It has

特性 Features

of low dropout (maximum 300mV at 1A), a verylow quiescent current (typically 300uA at 0.1A).The output voltage can be set from 0.5V to (VIN - VD) with anexternal resistor divider and it has ±2% accuracy through alltemperature ranges include the line as well as load variations. It isallowed to use a small 4.7μF MLCC input and output capacitor todeliver the current with the stable operation.Built-in Soft-Start function reduces the inrush current and theother features are include over current protection (OCP),short-circuit protection (SCP), and thermal shut down protection(TSD).FEATURES Input Voltage Range: 2.5V~6.0V Supply Current : (Typ.) 300uA Current limit : (Min.) 1.6A Adjustable Output from 0.5V LR2915: Typ 0.4V Dropout @ IOUT=1.5A Compatible with MLCC Capacitors Built-in Soft-Start Limits Inrush Current Built-in Thermal Shutdown Protection Built-in Over Current & Short Circuit Protection
