description

The TPS76201 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

regulator’s ultralow power operation make the

TPS76201 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 5-terminal small outline integrated-circuit SOT-23 package, the TPS76201 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. Since the PMOS pass element is a voltage-driven device, the quiescent

current is ultralow (30 µA maximum) and is stable over the entire range of output load current (10 µA 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 also features a logic-enabled sleep mode to shut down the regulator, reducing quiescent current

to 1 µA typical at T

= 25°C. The TPS76201 is offered in an adjustable version (programmable over the range

of 0.7 V to 5.5 V).

SLVS323B − FEBRUARY 2001 − REVISED JANUARY 2007 APPLICATION INFORMATION The TPS76201 low-dropout (LDO) regulator has been optimized for use in battery-operated equipment including, but not limited to, the sub 1.2-V DSP core voltage supplies. It features low quiescent current (23 µA nominally) and enable inputs to reduce supply currents to 1 µA when the regulators are turned off. A typical application circuit is shown in Figure 17.
PAGE 8
SLVS323B − FEBRUARY 2001 − REVISED JANUARY 2007 APPLICATION INFORMATION output voltage programming The output voltage of the TPS76201 adjustable regulator is programmed using an external resistor divider as shown in Figure 18. The output voltage is calculated using: V O +V ǒ1 ) R1 Ǔ R2 ref (1) Where: Vref = 0.6663 V typ (the internal reference voltage) Resistors R1 and R2 should be chosen for approximately 10-µA divider current.
PAGE 9
SLVS323B − FEBRUARY 2001 − REVISED JANUARY 2007 APPLICATION INFORMATION power dissipation and junction temperature Specified regulator operation is assured to a junction temperature of 125°C; the maximum junction temperature should be restricted to 125°C under normal operating conditions. This restriction limits the power dissipation the regulator can handle in any given application.
