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
low dropout voltages and quiescent currents
300
compared to conventional LDO regulators.
Offered in small-outline integrated-circuit (SOIC)
packages and 8-terminal thin shrink small-outline
(TSSOP), the TPS72xx series devices are ideal
for cost-sensitive designs and for designs where
board space is at a premium.

IO – Output Current – mA
Because the PMOS pass element behaves as a
low-value resistor, the dropout voltage is very low
– maximum of 85 mV at 100 mA of load current
Figure 1. Typical Dropout Voltage Versus
Output Current
(TPS7250) – and is directly proportional to the
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.
TPS7233
200250
The TPS72xx also features a logic-enabled sleep mode to shut down the regulator, reducing quiescent current
to 0.5 µA maximum at T
= 25°C. Other features include a power-good function that reports low output voltage
J
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).
