TPS720xx

www.ti.com ............................................................................................................................................................. SBVS100A–JUNE 2008–REVISED JUNE 2008

350mA, Ultra-Low V , RF Low-Dropout Linear Regulator with Bias Pin

FEATURES

DESCRIPTION

•

350mA High-Performance LDO

The TPS720xx family of dual rail, low-dropout linear

regulators (LDOs) offers outstanding ac performance

(PSRR, load and line transient response), while

consuming a very low quiescent current of 38µA.

•

Low Quiescent Current: 38µA

Excellent Load Transient Response:

±15mV for I_LOAD= 0mA to 350mA in 1µs

The V_BIASrail that powers the control circuit of the

LDO draws very low current (on the order of the

quiescent current of the LDO) and can be connected

to any power supply that is equal to or greater than

1.4V above the output voltage. The main power path

is through V_IN, which can be a lower voltage than

V_BIAS; it can be as low as V_OUT+ V_DO, increasing the

efficiency of the solution in many power-sensitive

applications. For example, V_INcan be an output of a

high-efficiency, dc-dc step-down regulator.

•

Excellent Line Transient Response:

ΔV_OUT= ±2mV for ΔV_BIAS= ±600mV in 1µs

ΔV_OUT= ±200µV for ΔV_IN= ±400mV in 1µs

•

Low Noise: 48µV_RMS(10Hz to 100kHz)

80dB V_INPSRR (10Hz to 10kHz)

70dB V_BIASPSRR (10Hz to 10kHz)

Fast Start-Up Time: 140µs

Inrush Current-Controlled Soft-Start with

Monotonic V_OUTRise and V_INCurrent Limited

to 100mA + I_LOAD

The TPS720xx supports a novel feature in which the

output of the LDO regulates under light loads when

the IN pin is left floating. The light-load drive current

is sourced from V_BIASunder this condition. This

feature is particularly useful in power-saving

applications where the dc/dc converter connected to

the IN pin is disabled but the LDO is still required to

regulate the voltage to a light load.

•

Over-Current and Thermal Protection

Low Dropout: 110mV at I_LOAD= 350mA

Stable with 2.2µF Output Capacitor

Available in 1,33mm x 0,96mm 5-Pin WCSP

APPLICATIONS

The TPS720xx is stable with ceramic capacitors and

uses an advanced BICMOS fabrication process that

yields a dropout of 110mV at a 350mA output load.

The TPS720xx has the unique feature of providing a

monotonic V_OUTrise (overshoot limited to ±3%) with

V_INinrush current limited to 100mA + I_LOADwith an

output capacitor of 2.2µF.

•

Digital Cameras

Cellular Camera Phones

Wireless LAN

Handheld Products

The TPS720xx uses a precision voltage reference

and feedback loop to achieve overall accuracy of 2%

over load, line, process, and temperature extremes.

An ultra-small wafer chip-scale package (WCSP)

makes the TPS720xx ideal for handheld applications.

This family of devices is fully specified over the

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