TPS727

SBVS128F –JUNE 2009–REVISED DECEMBER 2015

TPS727 250-mA, Ultralow I_Q, Fast Transient Response,

RF Low-Dropout Linear Regulator

1 Features

3 Description

The TPS727 family of low-dropout (LDO) linear

regulators are ultralow quiescent current LDOs with

excellent line and ultra-fast load transient

performance and are designed for power-sensitive

applications. The LDO output voltage level is preset

by the use of innovative factory EEPROM

•

Very Low Dropout:

–

65 mV Typical at 100 mA

130 mV Typical at 200 mA

163 mV Typical at 250 mA

•

2% Accuracy Over Load, Line, Temperature

programming.

precision band-gap and error

Ultralow I_Q: 7.9 μA

amplifier provides overall 2% accuracy over load, line,

and temperature extremes. The TPS727 family is

available in 1.5-mm × 1.5-mm SON and wafer chip-

scale (WCSP) packages that make the devices ideal

for handheld applications. This family of devices is

fully specified over a temperature range of T_J

–40°C to +125°C.

Excellent Load Transient Performance:±50 mV for

200 mA Loading and Unloading Transient

•

Available in Fixed-Output Voltages From 0.9 V to

5 V Using Innovative Factory EEPROM

Programming

•

High PSRR: 70 dB at 1 kHz

Stable with a 1.0-μF Ceramic Capacitor

Thermal Shutdown and Overcurrent Protection
