description  
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 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 ultra low  
(28 µA 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.
