description  
IN  
The TPS71xx integrated circuits are a family  
of micropower low-dropout (LDO) voltage  
regulators. An order of magnitude reduction in  
dropout voltage and quiescent current over  
conventional LDO performance is achieved by  
replacing the typical pnp pass transistor with a  
PMOS device.  
IN  
NC  
NC – No internal connection  
SENSE – Fixed voltage options only  
(TPS7133, TPS7148, and TPS7150)  
FB – Adjustable version only (TPS7101)  
†
‡
Because the PMOS device behaves as a low-value resistor, the dropout voltage is very low (maximum of 32  
mV at an output current of 100 mA for the TPS7150) and is directly proportional to the output current (see  
Figure 1). Additionally, since the PMOS pass element is a voltage-driven device, the quiescent current is very  
low and remains independent of output loading (typically 285 µA over the full range of output current, 0 mA to  
500 mA). These two key specifications yield a significant improvement in operating life for battery-powered  
systems. The LDO family also features a sleep mode; applying a TTL high signal to EN (enable) shuts down  
the regulator, reducing the quiescent current to 0.5 µA maximum at T = 25°C.
