3 Description

The TPS715 low-dropout (LDO) linear voltage

regulator is low quiescent current device that offers

the benefits of a wide input voltage range and lowpower

operation in miniaturized packaging. Thus, the

TPS715 is designed for battery-powered applications

and as a power-management attachment to lowpower

microcontrollers.

The TPS715 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 1.205 V to 15 V. The TPS715

LDOs support 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

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.
