DESCRIPTION
The TPS71550 low-dropout (LDO) voltage regulator offers the benefits of high input voltage, low-dropout voltage,
low-power operation, and miniaturized packaging. The TPS71550, which operates over an input range of 5 V to
24 V, is stable with any capacitor (≥ 0.47 µF). The low-dropout voltage and low quiescent current allow
operations at extremely low power levels. Therefore, the TPS71550 is ideal for powering battery management
ICs. Specifically, since the TPS71550 is enabled as soon as the applied voltage reaches the minimum input
voltage, the output is quickly available to power continuously operating battery charging ICs.
The usual PNP pass transistor has been replaced by a PMOS pass element.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 low-dropout voltage, typically 415 mV at 50 mA of load current, is directly
proportional to the load current. The low quiescent current is stable over the entire range of output load current.

Processing is per the Texas Instruments commercial production baseline and is in compliance with the Texas Instruments Quality
Control System in effect at the time of manufacture. Electrical screening consists of DC parametric and functional testing at room
temperature only. Unless otherwise specified by Texas Instruments AC performance and performance over temperature is not
warranted. Visual Inspection is performed in accordance with MIL-STD-883 Test Method 2010 Condition B at 75X minimum.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
