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 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

擄C
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
碌A(chǔ)
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

and 5-V fixed-voltage versions and in a variable version (programmable over the range of 1.2 V to 5.5 V).
