3 Description
The TPS715A 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 TPS715A is designed for battery-powered
applications and as a power-management attachment
to low-power microcontrollers.
The TPS715A 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 15 V. The TPS715A LDOs support 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 TPS715A (new chip) 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 TPS715A is available in a 3-mm × 3-mm package
for use in high power dissipation applications and a
small 2-mm × 2-mm package for hand-held and ultraportable
applications. The 3-mm × 3-mm package is
also available as a non-magnetic package for medical
imaging applications.
