description

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 designed to have fast transient response for larger load current changes.

Because the PMOS device behaves as a low-value resistor, the dropout voltage is very low (typically 210 mV at an

output current of 2 A for the TPS75x33) and is directly proportional to the output current. Additionally, since the

PMOS pass element is a voltage-driven device, the quiescent current is very low and independent of output loading

(typically 75 µA over the full range of output current, 1 mA to 2 A). These two key specifications yield a significant

improvement in operating life for battery-powered systems.

The device is enabled when the EN pin is connected to a low-level input voltage. This LDO family also features a

sleep mode; applying a TTL high signal to EN (enable) shuts down the regulator, reducing the quiescent current

to 1 µA at T = 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 when the regulated output voltage is pulled below 95% (i.e., over load condition)

of its regulated voltage.
