TPS75415-Q1 2-A Low-Dropout Voltage Regulators

The TPS752xx and TPS754xx are low-dropout regulators with integrated power-on reset and power good (PG) functions, respectively. These devices are capable of supplying 2 A of output current with a dropout of 210 mV (TPS75233, TPS75433). Quiescent current is 75 µA at full load and drops down to 1 µA when the device is disabled. TPS752xx and TPS754xx are desig.

Features

a sleep mode; applying a TTL high signal to EN (enable) shuts down the regulator, reducing the quiescent current to 1 µA at TJ = 25°C. The RESET (SVS, POR, or power on reset) output of the TPS752xx initiates a reset in microcomputer and microprocessor systems in the event of an undervoltage condition. An internal comparator in the TPS752xx monitors the output voltage of the regulator to detect an undervoltage condition on the regulated output voltage. When the output reaches 95% of its regulated voltage, RESET goes to a high-impedance state after a 100-ms delay. RESET goes to a logic-low state.
