3 Description
The TPS769xx-Q1 family of low-dropout (LDO)
voltage regulators offers the benefits of low-dropout
voltage, ultralow-power operation, and miniaturized
packaging. These regulators feature low-dropout
voltages and ultralow quiescent current compared to
conventional LDO regulators. Offered in a 5-pin small
outline integrated-circuit SOT-23 package, the
TPS769xx-Q1 series of 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-Q1),
and is directly proportional to the load current.
Because 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.

5 Description (continued)
The TPS769xx-Q1 devices also feature a logic-enabled sleep mode to shut down the regulator, reducing
quiescent current to 1 µA (typical) at TJ = 25°C. The TPS769xx-Q1 devices are offered in 1.2-V, 1.5-V, 1.8-V,
2.5V, 2.7-V, 2.8-V, 3-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).
