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
A 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

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