DESCRIPTION
This device is designed to have an ultralow quiescent
current and be stable with a 4.7-µF capacitor. This
combination provides high performance at a
reasonable cost.
Because the PMOS device behaves as a low-value
resistor, the dropout voltage is very low (typically 230
mV at an output current of 250 mA for the TPS76650)
and is directly proportional to the output current.
Additionally, since the PMOS pass element is a
voltage-driven device, the quiescent current is very
low and independent of output loading (typically 35
µA over the full range of output current, 0 mA to 250
mA). These two key specifications yield a significant
improvement in operating life for battery-powered
systems. This LDO family also features a sleep
mode; applying a TTL high signal to EN (enable)
shuts down the regulator, reducing the quiescent
current to less than 1 µA (typ).
Power good (PG) is an active high output that can be
used to implement a power-on reset or a low-battery
indicator.
The TPS766xx is offered in 1.5 V, 1.8 V, 2.5 V, 2.7 V,
2.8 V, 3.0 V, 3.3 V and 5.0 V fixed voltage versions
and in an adjustable version (programmable over the
range of 1.25 V to 5.5 V). Output voltage tolerance is
specified as a maximum of 3% over line, load, and
temperature ranges. The TPS766xx family is
available in an 8-pin SOIC package.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

(1) To calculate the minimum input voltage for your maximum output current, use the following equation: VI(min) = VO(max) + VDO(max load)
(2) Continuous current and operating junction temperature are limited by internal protection circuitry, but it is not recommended that the
device operate under conditions beyond those specified in this table for extended periods of time.
