LOW DROPOUT VOLTAGE REGULATORS
FEATURES 1 250-mA Low Dropout Voltage Regulator Available in 1.5 V, 1.8 V, 2.5 V, 2.7 V, 2.8 V,
3.0 V, 3.3 V, 5.0 V Fixed Output and Adjustable
Versions Dropout Voltage to 140 mV (Typ) at 250 mA
(TPS76650) Ultralow 35-ВµA Typical Quiescent Current 3% Tolerance Over Specified Conditions for
Fixed Output Versions Open-Drain Power Good 8-Pin SOIC Package Thermal Shutdown Protection
2 DESCRIPTION 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. VDO -Output Voltage -V This device is designed to have an ultralow quiescent
current and be stable with a 4.7-ВµF capacitor. This
combination provides high performance at a
reasonable cost. Because the PMOS device behaves as a low-value …
