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). 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 TJ = 25°C.The
TPS763xx is offered in 1.6-V ,1.8-V, 2.5-V, 2.7-V,
2.8-V, 3-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).
