description
The TPS769xx 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
regulators. Offered in a 5-terminal small outline

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 A maximum) and is stable over the entire range
of output load current (0 mA to 100 mA). Intended for use in portable systems such as laptops and cellular
phones, the ultralow-dropout voltage feature and ultralow-power operation result in a significant increase in
system battery operating life.
The TPS769xx also features a logic-enabled sleep mode to shut down the regulator, reducing quiescent current
to 1 A 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,
J
and 5-V fixed-voltage versions and in a variable version (programmable over the range of 1.2 V to 5.5 V).
