The TPS769xx-Q1 family of low-dropout (LDO)
voltage regulators offers the benefits of low dropout
19
IO = 100 mA
voltage, ultralow-power operation, and miniaturized
packaging. These regulators feature low dropout
voltages and ultralow quiescent current compared to
18
conventional LDO regulators. Offered in a 5-terminal
IO = 0 mA
small outline integrated-circuit SOT-23 package, the
17
TPS769xx-Q1 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,

TA – Free-Air Temperature – °C
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. 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-Q1 also features a logic-enabled sleep mode to shut down the regulator, reducing quiescent current
to 1 µA typical at T_J = 25°C. The TPS769xx-Q1 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).
