description
The TPS769xx family of low-dropout (LDO) voltage
regulators offers the benefits of low dropout voltage,
ultralow-power
operation,
packaging. These regulators feature low dropout
voltages and ultralow quiescent current compared to
conventional LDO regulators. Offered in a 5-terminal
small outline integrated-circuit SOT-23 package, the
TPS769xx 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 71 mV at 100
mA of load current (TPS76950), and is directly
proportional to the load current. Since the PMOS pass
element is a voltage-driven device, the quiescent current is ultralow (28 µA maximum) and is stable over the entire
range of output load current (0 mA to 100 mA). The ultralow-dropout voltage feature and ultralow-power operation
result in a significant increase in system battery operating life, making this device suitable for use in automotive
applications.
The TPS769xx also features a logic-enabled sleep mode to shut down the regulator, reducing quiescent current to
1 µA typical at T
= 25°C. The TPS769xx 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).
