• 350mA High-Performance LDO

The TPS720xx family of dual rail, low-dropout linear

regulators (LDOs) offers outstanding ac performance

• Low Quiescent Current: 38µA

(PSRR, load and line transient response), while

• Excellent Load Transient Response:

consuming a very low quiescent current of 38

µA.

±15mV for ILOAD = 0mA to 350mA in 1µs

The VBIAS rail that powers the control circuit of the

• Excellent Line Transient Response:

LDO draws very low current (on the order of the

ΔVOUT = ±2mV for ΔVBIAS = ±600mV in 1µs

quiescent current of the LDO) and can be connected

ΔVOUT = ±200µV for ΔVIN = ±400mV in 1µs

to any power supply that is equal to or greater than

1.4V above the output voltage. The main power path

is through VIN, which can be a lower voltage than

• 80dB V

VBIAS; it can be as low as VOUT + VDO, increasing the

applications. For example, VIN can be an output of a

• Inrush Current-Controlled Soft-Start with

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

Monotonic VOUT Rise and VIN Current Limited

The TPS720xx supports a novel feature in which the

to 100mA + ILOAD

output of the LDO regulates under light loads when

• Over-Current and Thermal Protection

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

is sourced from VBIAS under this condition. This

LOAD = 350mA

feature

is

particularly

useful

in

power-saving

• Stable with 2.2µF Output Capacitor

applications where the dc/dc converter connected to

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

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

regulate the voltage to a light load.

The TPS720xx is stable with ceramic capacitors and

• Digital Cameras

uses an advanced BICMOS fabrication process that

• Cellular Camera Phones

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

The TPS720xx has the unique feature of providing a

• Wireless LAN

monotonic VOUT rise (overshoot limited to ±3%) with

• Handheld Products

VIN inrush current limited to 100mA + ILOAD with an

output capacitor of 2.2

µF.

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 TJ = –40°C to +125°C.
