TPS752xxQ with RESET Output, TPS754xxQ with Power Good Output

FAST-TRANSIENT-RESPONSE 2-A LOW-DROPOUT VOLTAGE REGULATORS

FEATURES

DESCRIPTION

•

2-A Low-Dropout Voltage Regulator

The TPS752xxQ and TPS754xxQ devices 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 (TPS75233Q,

TPS75433Q). Quiescent current is 75 μA at full load

and drops down to 1 μA when the device is disabled.

These devices are designed to have fast transient

response for larger load current changes.

•

Available in 1.5 V, 1.8 V, 2.5 V, 3.3 V Fixed

Output and Adjustable Versions

Open Drain Power-On Reset With 100ms Delay

(TPS752xxQ)

Open Drain Power-Good (PG) Status Output

(TPS754xxQ)

Dropout Voltage Typically 210 mV at 2 A

(TPS75233Q)

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

TPS75x33Q) and is directly proportional to the output

current. Additionally, because 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.

DSP, FPGA Supplies

The device is enabled when EN 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 less than 1 μA at T_J= +25°C.
