PMOS device. Because the PMOS device behaves as a low-value resistor, the dropout voltage is very low (maximum of 32 m V at an output current of 100 m A 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 m A to m A). 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 TJ = 25°C.

Frequently Asked Questions

What improvements do these regulators offer for battery systems?

Due to the PMOS pass element, they feature very low quiescent current and dramatically reduced dropout voltage, improving operating life.

Can I detect a power-down or reset event using this regulator?

Yes, the Power-Good (PG) status output can be used to implement either a power-on reset circuit or a low-battery indicator.

What packages are available for the TPS71xx family?

The family is available in PDIP, SO, and TSSOP packages. The TSSOP option offers a reduced component height of 1.2 mm.

Is there an adjustable voltage option within this series?

Yes, the TPS7101 is the adjustable version (programmable between 1.2 V and 9.75 V) and requires an external resistor divider for programming.
