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-terminal

small outline integrated-circuit SOT-23 package, the

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,

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

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

5.5 V).
