The TPS770xx 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

package,  
the  
TPS770xx 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 35 mV at 50 mA of

load current (TPS77050) — 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  
ofoutputloadcurrent(0mAto50mA). Intendedforuseinportablesystemssuchaslaptopsandcellularphones,  
the ultralow-dropout voltage feature and ultralow-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 µA typical at T = 25°C. 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).
