Preliminary

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

RT9012 offers 2% accuracy, extremely low dropout voltage

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

only 27μA 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 27μA/LDO

^zHigh Output Accuracy 2%

^zShort Circuit Protection

^zThermal Shutdown Protection

RT9012 is short circuit thermal folded back protected.

RT9012 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

RT9012 can operate stably with very small ceramic output

capacitors, reducing required board space and component

cost. 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
