Texas Instruments TPS71550DCKR, 1 Low Dropout Voltage, Voltage Regulator 50mA, 5 V 5-Pin, SC-70

The Texas Instruments TPS715 low-dropout (LDO) voltage regulators offer the benefits of high input voltage, low-dropout 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 greater than or equal to 0.47 μF. The low dropout voltage and low quiescent current allow operation at extremely low power levels. Therefore, the devices are ideal for powering battery management ICs. Specifically, because 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.

LDO (Low Dropout) Linear Voltage Regulators, Texas Instruments

A range of Texas Instruments Low Dropout (LDO) Linear Voltage regulators. LDO voltage regulators are able to operate with a small input-output differential making them suitable for a variety of applications where conventional regulators would be unsatisfactory. The latest generation of LDO regulators offers low quiescent current levels and reduced output noise together with excellent line voltage regulation and high PSRR.
