3 Description

The TPS763xx-Q1 family of low-dropout (LDO)

voltage regulators offers the benefits of low-dropout

voltage,

low-power

operation,

and

miniaturized

packaging. These regulators feature low dropout

voltages

and

quiescent

currents

compared

to

conventional LDO regulators. Offered in a 5-pin, small

outline

integrated-circuit

SOT-23

package,

the

TPS763xx-Q1 series devices are ideal for cost-

sensitive designs and for applications 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 pass element. Because

the PMOS pass element behaves as a low-value

resistor, the dropout voltage is low—typically 300 mV

at 150 mA of load current (TPS76333-Q1)—and is

directly proportional to the load current. Since the

PMOS pass element is a voltage-driven device, the

quiescent current is low (140

μA maximum) and is

stable over the entire range of output load current (0

mA to 150 mA). Intended for use in portable systems

such as laptops and cellular phones, the low-dropout

voltage feature and low-power operation result in a

significant increase in system battery operating life.

The TPS763xx-Q1 also features a logic-enabled

sleep mode to shut down the regulator, reducing

quiescent current to 1

TPS763xx-Q1 is offered in 1.6-V,1.8-V, 2.5-V, 3-V,

3.3-V, and 5-V fixed-voltage versions and in a

variable version (programmable over the range of 1.5

V to 6.5 V).
