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 5-terminal small outline integrated-circuit
SOT-23 package, the TPS763xx series devices are ideal for cost-sensitive designs and 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 very low—typically 300 mV at 150 mA of load current (TPS76333)—and is directly
proportional to the load current. Since the PMOS pass element is a voltage-driven device, the quiescent current
is very low (140 µA maximum) and is stable over the entire range of output load current (0 mA to 150 mA).
Intended for use in portable systems such as laptops and cellular phones, the low-dropout voltage feature and
low-power operation result in a significant increase in system battery operating life.
The TPS763xx also features a logic-enabled sleep mode to shut down the regulator, reducing quiescent current
to 1 µA maximum at T
= 25°C.The TPS763xx is offered in 1.6-V ,1.8-V, 2.5-V , 2.7-V, 2.8-V, 3.0-V , 3.3-V, 3.8-V ,

and 5-V fixed-voltage versions and in a variable version (programmable over the range of 1.5 V to 6.5 V.
