	description					22
	The TPS769xx	family of	low-dropout	(LDO)			VI = 4.3 V
						21	CO = 4.7 F
	voltage regulators offers the benefits of low
	dropout voltage, ultralow-power operation, and					20
	miniaturized packaging. These regulators feature				A
	low dropout voltages and		ultralow quiescent		±		IO = 100 mA
	current compared to conventional LDO				Current	19
	regulators. Offered in a 5-terminal small outline
	integrated-circuit	SOT-23	package,	the	Ground	18
	TPS769xx series devices are ideal for						IO = 0 mA
	micropower operations and where board space is					17
	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 TJ = 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, and 5-V fixed-voltage versions and in a variable version (programmable over the range of 1.2 V to 5.5 V).
