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 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 devices also feature a logic-enabled sleep mode to shut down the regulator, reducing

quiescent current to 1

V, 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).
