3 Description

The TPS763xx family of low-dropout (LDO) voltage

regulators offers the benefits of low-dropout voltage,

low-power operation, and miniaturized packaging.

These regulators feature low dropout voltages and

quiescent currents compared to conventional LDO

regulators. Offered in a 5-pin, small outline

integrated-circuit SOT-23 package, the TPS763xx

series devices are ideal for cost-sensitive designs

and for applications where board space is at a

premium.

A combination of new circuit design and process

innovation has enabled the usual pnp pass transistor

to be replaced by a PMOS pass element. Because

the PMOS pass element behaves as a low-value

resistor, the dropout voltage is low—typically 300 mV

at 150 mA of load current (TPS76333)—and is

directly proportional to the load current. Because the

PMOS pass element is a voltage-driven device, the

quiescent current is low (140 μA maximum) and is

stable over the entire range of output load current

(0 mA to 150 mA).
