SBVS095–AUGUST 2007

200mA Low-Dropout Linear Regulator

with Pin-Selectable Dual-Voltage Level Output

FEATURES

DESCRIPTION

•

Very Low Dropout: 230mV Typical at 200mA

3% Accuracy Over Load/Line/Temperature

Low I_Q: 50μA in Active Mode

The TPS728xx series of low-dropout linear regulators

(LDOs), with a selectable dual-voltage level output, is

designed specially for applications that require two

levels of output voltage regulation. Programming

fuses and memory cards, reducing leakage effects,

and conserving power in nanometric processes are

some application examples.

•

Available in Fixed-Output Voltages From 0.9V

to 3.6V Using Innovative Factory EEPROM

Programming

•

VSET Pin Toggles Output Voltage Between

Two Preset Levels

The VSET pin is used to select one of two output

voltage levels preset through innovative factory

EEPROM programming. A precision bandgap and

error amplifier provides an overall 3% accuracy over

load, line, and temperature extremes.

–

Preset Output Voltage Levels Can Be

EEPROM-Programmed To Any Combination

•

High PSRR: 65dB at 1kHz

Ultra-small wafer chip scale (WCSP) and 2mm x

2mm SON packages make the TPS728xx series ideal

for handheld applications.

Stable with a 1.0μF Ceramic Capacitor

Thermal Shutdown and Over-Current

Protection

This family of devices is fully specified over a

temperature range of T_J= –40°C to +125°C.
