description
The TPS770xx family of low-dropout (LDO) voltage regulators offers the benefits of low dropout voltage, ultra
low-power operation, and miniaturized packaging. These regulators feature low dropout voltages and ultra low
quiescent current compared to conventional LDO regulators. Offered in a 5-terminal small outline
integrated-circuit SOT-23 package, the TPS770xx series devices are ideal for micropower operations 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 35 mV at 50 mA of load current (TPS77050) — and is directly proportional
to the load current. Since the PMOS pass element is a voltage-driven device, the quiescent current is ultra low
(28
μ
A maximum) and is stable over the entire range of output load current (0 mA to 50 mA).
Intended for use in portable systems such as
laptops and cellular phones, the ultra low-dropout
voltage feature and ultra low-power operation
result in a significant increase in system battery
operating life.
The TPS770xx also features a logic-enabled
sleep mode to shut down the regulator, reducing
quiescent current to 1

TPS770xx is offered in 1.2-V, 1.5-V, 1.8-V, 2.5-V,
2.7-V, 2.8-V, 3.0-V, 3.3-V, and 5-V fixed-voltage
versions and in a variable version (programmable
over the range of 1.2 V to 5.5 V).
