The TPS72xx family of low-dropout (LDO) voltage

regulators offers the benefits of low-dropout

voltage, micropower operation, and miniaturized

packaging. These regulators feature extremely

low dropout voltages and quiescent currents

compared to conventional LDO regulators.

Offered in small-outline integrated-circuit (SOIC)

packages and 8-terminal thin shrink small-outline

(TSSOP), the TPS72xx series devices are ideal

for cost-sensitive designs and for designs where

board space is at a premium.

A combination of new circuit design and process

innovation has enabled the usual pnp pass

transistor to be replaced by a PMOS device.

Because the PMOS pass element behaves as a

low-value resistor, the dropout voltage is very low

– maximum of 85 mV at 100 mA of load current

(TPS7250) – and is directly proportional to the

load current (see Figure 1). Since the PMOS pass

– Output Current – mA

Figure 1. Typical Dropout Voltage Versus

Output Current

element is a voltage-driven device, the quiescent current is very low (300 µA maximum) and is stable over the

entire range of output load current (0 mA to 250 mA). Intended for use in portable systems such as laptops and

cellular phones, the low-dropout voltage and micropower operation result in a significant increase in system

battery operating life.

The TPS72xx also features a logic-enabled sleep mode to shut down the regulator, reducing quiescent current

to 0.5 µA maximum at T = 25°C. Other features include a power-good function that reports low output voltage

and may be used to implement a power-on reset or a low-battery indicator.

The TPS72xx is offered in 2.5-V, 3-V, 3.3-V, 4.85-V, and 5-V fixed-voltage versions and in an adjustable version

(programmable over the range of 1.2 V to 9.75 V). Output voltage tolerance is specified as a maximum of 2%

over line, load, and temperature ranges (3% for adjustable version).

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of

Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of Texas Instruments

standard warranty. Production processing does not necessarily include

testing of all parameters.
