The TPS72xx family of low-dropout (LDO) voltage
regulators offers the benefits of low-dropout
voltage, micropower operation, and miniaturized
packaging. These regulators feature extremely

TPS7250
A combination of new circuit design and process
innovation has enabled the usual pnp pass
transistor to be replaced by a PMOS device.
Because the PMOS pass element behaves as a

IO – Output Current – mA
low-value resistor, the dropout voltage is very low
– maximum of 85 mV at 100 mA of load current
(TPS7250) – and is directly proportional to the
Figure 1. Typical Dropout Voltage Versus
Output Current
load current (see Figure 1). Since the PMOS pass
element is a voltage-driven device, the quiescent current is very low (300 µA maximum) and is stable over the
entire range of output load current (0 mA to 250 mA). Intended for use in portable systems such as laptops and
cellular phones, the low-dropout voltage and micropower operation result in a significant increase in system
battery operating life.
The TPS72xx also features a logic-enabled sleep mode to shut down the regulator, reducing quiescent current
to 0.5 µA maximum at TJ = 25°C. Other features include a power-good function that reports low output voltage
and may be used to implement a power-on reset or a low-battery indicator.
The TPS72xx is offered in 2.5-V, 3-V, 3.3-V, 4.85-V, and 5-V fixed-voltage versions and in an adjustable version
(programmable over the range of 1.2 V to 9.75 V). Output voltage tolerance is specified as a maximum of 2%
over line, load, and temperature ranges (3% for adjustable version).
