1 / 4 page TPS71550-DIE www.ti.com SLVSBG8 – JULY 2012 LOW-DROPOUT LINEAR REGULATOR Check for Samples: TPS71550-DIE 1 FEATURES • 24-V Maximum Input Voltage APPLICATIONS • Low Quiescent Current • Ultra-Low Power Microcontrollers • Low-Dropout Regulator • Cellular/Cordless Handsets • Available in 5 V • Portable/Battery-Powered Equipment • Minimum/Maximum Specified Current Limit xxx 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 The usual PNP pass transistor has been replaced by a PMOS pass element.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. xxx ORDERING INFORMATION(1) PACKAGE PRODUCT PACKAGE ORDERABLE PART NUMBER PACKAGE QUANTITY DESIGNATOR TPS71550TDB1 400 TPS71550 TD(2) Bare die in waffle pack TPS71550TDB2 10 (1) For the most current package and ordering information, see the Package Option Addendum at the end of this document, or see the TI web site at www.ti.com.
