RT2517AGQV

LDO电压稳压器, 可调, 2.2 V至6 V输入, 150 mV压降, 1.2 V至5 V/1 A输出, VDFN-8

The from is an ultra low dropout LDO linear regulator in 8 pin VDFN package. It is a high performance positive voltage regulator designed for applications requiring low input voltage and ultra low dropout voltage at up to 1A. The feature of ultra low dropout voltage is ideal for applications where output voltage is very close to input voltage. The input voltage can be as low as 2.2V and the output voltage is adjustable by an external resistive divider. The RT2517A provides an excellent output voltage regulation over variations in line, load and temperature. Current limit and thermal shutdown functions are provided. Additionally, an enable pin is designed to further reduce power consumption while shutdown and the shutdown current is as low as 0.1µA. It is typically used in automotive audio, navigation & info systems, general purpose point of load, digital set top boxes and vehicle electronics.
