Overview
Preliminary RP1227 Adjustable, 300mA LDO Regulator with Enable General Description The RP1227 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 RP1227 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 overtemperature protection.
The device has enable pin to reduce power consumption in shutdown mode.
The devices is available in the popular SOT-23-5 package.
Ordering Information RP1227 Package Type B : SOT-23-5 Operating Temperature Range G : Green (Halogen Free with Commer- cial Standard) Note : Richpower Green products are : RoHS compliant and compatible with the current requirements of IPC/JEDEC J-STD-020.
Suitable for use in SnPb or Pb-free soldering processes.
