regulators offers the benefits of low-dropout

voltage, micropower operation, and miniaturized
packaging. These regulators feature extremely
300
low dropout voltages and quiescent currents
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.
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
low-value resistor, the dropout voltage is very low
Figure 1. Typical Dropout Voltage Versus
Output Current
– maximum of 85 mV at 100 mA of load 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

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 , 2.75-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).

Minimum input voltage defined in the recommended operating conditions is the maximum specified output voltage plus dropout voltage at the
maximum specified load range. Since dropout voltage is a function of output current, the usable range can be extended for lighter loads. To
