Low-Dropout Linear Regulator in SC70 Package

The TPS715xx low-dropout (LDO) voltage regulators
offer the benefits of high input voltage, low-dropout

range of 2.5 V to 24 V, are stable with any capacitor
Available in 2.5 V, 3.0 V, 3.3 V, 5.0 V, and
(> 0.47 F). The low dropout voltage and low
quiescent current allow operations at extremely low
Adjustable (12 V to 15 V)
power levels. Therefore, the devices are ideal for
Minimum/Maximum Specified Current Limit
powering battery management ICs. Specifically, since
5-Pin SC70/SOT-323 (DCK) Package
the devices are enabled as soon as the applied
voltage reaches the minimum input voltage, the

operating battery charging ICs.
The usual PNP pass transistor has been replaced by
Ultra Low Power Microcontrollers
a PMOS pass element. Because the PMOS pass
element behaves as a low-value resistor, the low

dropout voltage, typically 415 mV at 50 mA of load

current, is directly proportional to the load current.
The low quiescent current (3.2 A typically) is stable
over the entire range of output load current (0 mA to
50 mA).
