3 Description

The TPS714 low-dropout (LDO) linear voltage

regulator is a low quiescent current device that

offers the benefits of a wide input voltage range

and low-power operation in miniaturized packaging.

Thus, the TPS714 is designed for battery-powered

applications and as a power-management attachment

to low-power microcontrollers.

The TPS714 is available in both fixed and adjustable

versions. For more flexibility or higher output voltages,

the adjustable version uses external feedback

resistors to set the output voltage from 1.205 V to

8.8 V. The TPS714 LDO supports a low dropout of

650 mV (typ) at 80 mA of load current. The low

quiescent current (3.2 μA typically) is stable over

the entire range of output load current (0 mA to 80

mA). The TPS714 (new chip only) also features an

internal soft-start to lower the inrush current. The builtin

overcurrent limit helps protect the regulator in the

event of a load short or fault.

The TPS714 is available in a 2-mm × 2-mm package

for use in high power dissipation applications and the

SC70-5 package is designed for hand-held and ultraportable

applications.
