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 μA typical at T_J = 25°C. The TPS769xx-Q1 devices are offered in 1.2-V, 1.5-V, 1.8-V, 2.5-
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).
