DESCRIPTION

The TPS76201-Q1 low-dropout (LDO) voltage

regulator features an adjustable output voltage as low

as 0.7 V. It is an ideal regulator for sub 1.2-V DSP

core voltage supplies and is equally suited for similar

applications with other low-voltage processors and

controllers. SOT-23 packaging and the high-efficiency

that results from the ultralow power regulator

operation make the TPS76201-Q1 especially useful

in handheld and portable battery applications. This

regulator features low dropout voltages and ultralow

quiescent current compared to conventional LDO

regulators. Offered in a five-terminal, small outline

integrated circuit (SOT-23) package, the

TPS76201-Q1 is ideal for micropower operations and

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 is a voltage-driven device,

the quiescent current is ultralow (30 mA maximum)

and is stable over the entire range of output load

current (10 mA to 100 mA). Intended for use in

portable systems such as laptops and cellular

phones, the ultralow-power operation results in a

significant increase in the system battery operating

life.

The TPS76201-Q1 also features a logic-enabled

sleep mode to shut down the regulator, reducing

quiescent current to 1 mA typical at TJ = +25°C. The

TPS76201-Q1 is offered in an adjustable version

(programmable over the range of 0.7 V to 5.5 V).
