The TPS71025 low-dropout regulator offers an  
order of magnitude reduction in both dropout  
voltage and quiescent current over conventional  
LDO performance. The improvement results from  
replacing the typical pnp pass transistor with a  
PMOS device.

NC  
NC – No internal connection  
Because the PMOS device behaves as a low-value resistor, the dropout voltage is very low (maximum of 95 mV  
at an output current of 100 mA) 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 292 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  
TPS71025 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.
