RT9179APS Product Details

The RT9179APS is a high performance linear voltage regulator with enable high function and adjustable output with a 1.175V reference voltage. It operates from an input of 3V to 5.5V and provides output current up to 500mA with two external resistors to set the output voltage ranges from 1.175V to 4.5V.The RT9179APS has superior regulation over variations in line and load. Also it provides fast response to step changes in load. Other features include over-current and over-temperature protection. The device has enable pin to reduce power consumption in shutdown mode.The device is available in SOP-8 package.
