DESCRIPTION
The TPS737xx family of linear low-dropout (LDO)
voltage regulators uses an NMOS pass element in a
voltage-follower
configuration.
relatively insensitive to output capacitor value and
ESR, allowing a wide variety of load configurations.
Load transient response is excellent, even with a
small 1.0μF ceramic output capacitor. The NMOS
topology also allows very low dropout for the die size
used.
APPLICATIONS
Point of Load Regulation for DSPs, FPGAs,
ASICs, and Microprocessors
Post-Regulation for Switching Supplies

The TPS737xx family uses an advanced BiCMOS
process to yield high precision while delivering very
low dropout voltages and low ground pin current.
Current consumption, when not enabled, is under

A and ideal for portable applications. These
devices are protected by thermal shutdown and
foldback current limit.
