Description
RT9179GB Richtek USA Linear Voltage Regulator IC Positive Adjustable 1 Output 1.175 V to 4.5 V 300mA SOT-23-5, Tape and Reel (TR)
The RT9179 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 300mA with two external resistors to set the output voltage ranges from 1.175V to 4.5V.
The RT9179 has superior regulation over variations in line and load. Also it provides fast respond 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 devices is available in the popular SOT-23-5 package.
