description

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.

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.
