The TPS770xx family of low-dropout (LDO)voltage regulators offers the benefits of low dropout voltage, ultra low-power operation, and miniaturized packaging. These regulators feature low dropout voltages and ultra low quiescent current compared to conventional LDO regulators. Offered in a 5-terminal small outline integrated-circuit SOT-23 package, the TPS770xx series devices are ideal formicropower 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 35 mV at 50 mA of load current (TPS77050) -- and is directly proportional to the load current. Since the PMOS pass element isa voltage-driven device, the quiescent current is ultra low (28 uA maximum) and is stable over the entire range of output load current (0 mA to 50 mA). Intended for use in portable systems such as laptops and cellular phones,the ultra low-dropout voltage feature and ultra low-power operation result in a significant increase in system battery operating life. The TPS770xx also features a logic-enabled sleep mode to shut down the regulator, reducing quiescent current to 1 uA typical at T J = 25oC. The TPS770xx 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).
