3 Description

The TPS715-Q1 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 TPS715-Q1 is designed for battery-powered

applications and as a power-management attachment

to low-power microcontrollers.

The TPS715-Q1 is available in both fixed and

adjustable versions. For more flexibility or higher

output voltages, the adjustable version uses feedback

resistors to set the output voltage from 1.2 V to

15 V. The TPS715-Q1 LDO supports a low dropout

of typically 415 mV at 50 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 50 mA).

The TPS715-Q1 also features an internal soft-start to

lower the inrush current. The built-in overcurrent limit

helps protect the regulator in the event of a load short

or fault.

The TPS715-Q1 is available in a 2.00 mm × 1.25 mm,

5-pin SC-70 (DCK) package for fixed and adjustable

outputs.
