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-terminal, 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 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 TJ = 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.
