DESCRIPTION/ORDERING INFORMATION

One Fabrication Site

The TPS797xx family of low-dropout (LDO) voltage

regulators offers the benefits of low-dropout voltage

and ultralow-power operation. The device is stable

with any capacitor (> 0.47 µF). Therefore,

implementations of this device require little board

space due to the miniaturized packaging and

potentially small output capacitor. In addition, the

family includes an integrated open drain active-high

power good (PG) output. Intended for use in

microcontroller based, battery-powered applications,

Qualification Pedigree⁽¹⁾

10 mA Low-Dropout Regulator

Ultralow 1.2 µA Quiescent Current at 10 mA

5-Pin SC70/SOT-323 (DCK) Package

Integrated Power Good Output

the

TPS797xx

family's

low

dropout

and

ultralow-powered operation results in a significant

increase in system battery operating life. The small

packaging minimizes consumption of board space.

Stable With Any Capacitor (> 0.47 µF)

The device is enabled when the applied voltage

exceeds the minimum input voltage. The usual PNP

pass transistor has been replaced by a PMOS pass

element. Because the PMOS pass element behaves

as a low-value resistor, the dropout voltage is low,

125 mV (typ) at 10 mA of load current and is directly

proportional to the load current. The quiescent current

is ultralow (1.2 µA typ) and is stable over the entire

range of output load current (0 mA to 10 mA). When

properly configured with a pullup resistor, the PG

output can be used to implement a power-on reset or

low battery indicator. The TPS797xx is offered in

1.8 V, 3 V, and 3.3 V fixed options.

Dropout Voltage Typically 105 mV at 10 mA

Overcurrent Limitation

Component qualification in accordance with JEDEC and

industry standards to ensure reliable operation over an

extended temperature range. This includes, but is not limited

to, Highly Accelerated Stress Test (HAST) or biased 85/85,

temperature cycle, autoclave or unbiased HAST,

electromigration, bond intermetallic life, and mold compound

life. Such qualification testing should not be viewed as

justifying use of this component beyond specified

performance and environmental limits.
