RT9012

300mA Dual LDO Regulator with POR

General Description

Features

z Wide Operating Voltage Ranges : 2.5V to 5.5V

RT9012 is a dual channel, low noise, and low dropout with

the sourcing ability up to 300mA and power-on reset

function. The range of output voltage is from 1.2V to 3.6V

by operating from 2.5V to 5.5V input.

z Low-Noise for RF Application

z No Noise Bypass Capacitor Required

z Fast Response in Line/Load Transient

z TTL-Logic-Controlled Shutdown Input

z Low Temperature Coefficient

The RT9012 offers 2% accuracy, extremely low dropout

voltage (240mV @ 300mA), and extremely low ground

current, only 27uA per LDO. The shutdown current is near

zero current which is suitable for battery-power devices.

Other features include current limiting, over temperature,

output short circuit protection.

^zDual LDO Outputs (300mA/300mA)

^zUltra-low Quiescent Current 27uA/LDO

^zHigh Output Accuracy 2%

^zShort Circuit Protection

^zThermal Shutdown Protection

The RT9012 is short circuit thermal folded back protected.

The IC lowers its OTP trip point from 165°C to 110°C when

output short circuit occurs (VOUT < 0.4V) providing

maximum safety to end users.

^zCurrent Limit Protection

z Short Circuit Thermal Folded Back Protection

z Tiny 8-Lead WDFN Package

z RoHS Compliant and 100% Lead (Pb)-Free

The RT9012 can operate stably with very small ceramic

output capacitors, reducing required board space and

component cost. The RT9012 is available in fixed output

voltages in the WDFN-8L 2x2 package.

Applications

z CDMA/GSM Cellular Handsets

z Battery-Powered Equipment

z Laptop, Palmtops, Notebook Computers

z Hand-Held Instruments
