2 Description
The TPS715 low-dropout (LDO) linear voltage
regulators are low quiescent current devices that
offer the benefits of a wide input voltage range and
low-power operation in miniaturized packaging. The
low dropout voltage and low quiescent current of
the TPS715 allows operation at extremely low power
levels. Thus, the TPS715 is designed for batterypowered
applications and as a power-management
attachment to low-power 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.
