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.
