FAST-TRANSIENT RESPONSE 5-A LOW-DROPOUT VOLTAGE REGULATORS
FEATURES
DESCRIPTION
•
5-A Low-Dropout Voltage Regulator
The TPS756xx family of 5-A low dropout (LDO)
regulators contains four fixed voltage option regu-
lators and an adjustable voltage option regulator.
These devices are capable of supplying 5 A of output
current with a dropout of 250 mV (TPS75633).
Therefore, the device is capable of performing a
3.3-V to 2.5-V conversion.
•
Available in 1.5-V, 1.8-V, 2.5-V, and 3.3-V
Fixed-Output and Adjustable Versions
•
Dropout Voltage Typically 250 mV at 5 A
(TPS75633)
•
•
•
Low 125 µA Typical Quiescent Current
Fast Transient Response
Quiescent current is 125 µA at full load and drops
down to less than 1 µA when the device is disabled.
The TPS756xx is designed to have fast transient
response for large load current changes.
3% Tolerance Over Specified Conditions for
Fixed-Output Versions
