3 Description
The TPS74401 low-dropout (LDO) linear regulators
provide an easy-to-use robust power-management
option for a wide variety of applications. The userprogrammable
soft-start minimizes stress on the input
power source by reducing capacitive inrush current
on start-up. The soft-start is monotonic and designed
for powering many different types of processors
and application-specific integrated circuits (ASICs).
The enable input and power-good output allow
easy sequencing with external regulators. Complete
flexibility lets the user configure a plan that meets the
sequencing requirements of field-programmable gate
arrays (FPGAs), digital signal processors (DSPs), and
other applications with specific start-up requirements.
A precision reference and error amplifier deliver 1%
accuracy over load, line, temperature, and process.
The device is stable without an output capacitor
(legacy chip) or with any type of capacitor ≥ 2.2μF
(new chip). The device is fully specified from TJ = –
40°C to 125°C.
