DESCRIPTION  
The TPS715xx low-dropout (LDO) voltage regulators  
offer the benefits of high input voltage, LDO voltage,  
low-power operation, and miniaturized packaging.  
The devices, which operate over an input range of  
2.5 V to 24 V, are stable with any capacitor  
(>0.47 µF). The LDO voltage and low quiescent  
current allow operations at extremely low power  
levels. Therefore, the devices are ideal for powering  
battery-management ICs. Specifically, since the  
devices are enabled as soon as the applied voltage  
reaches the minimum input voltage, the output is  
quickly available to power continuously operating  
battery-charging ICs.  
24-V Maximum Input Voltage  
Low 3.2-µA Quiescent Current at 50 mA  
Stable With Any Capacitor (>0.47 µF)  
50-mA Low-Dropout Regulator  
Available in 2.5 V, 3 V, 3.3 V, 5 V, and  
Adjustable (1.2 V to 15 V)  
Minimum/Maximum Specified Current Limit  
5-Pin SC70/SOT-323 (DCK) Package  
–40°C to 125°C Specified Junction  
Temperature Range  
The usual PNP pass transistor has been replaced by  
a PMOS pass element. Because the PMOS pass  
element behaves as a low-value resistor, the LDO  
voltage, typically 415 mV at 50 mA of load current, is  
directly proportional to the load current. The low  
quiescent current (3.2 µA typ) is stable over the  
entire range of output load current (0 mA to 50 mA).

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam  
during storage or handling to prevent electrostatic damage to the MOS gates.
