TPS74401RGWT规格书详情

1 Features

• Input voltage range: 1.1V to 5.5V

• Adjustable start-up in-rush control

• 1% accuracy over line, load, and temperature

• VBIAS permits low VIN operation with good transient

response

• Adjustable output: 0.8V to 3.6V

• Ultra-low dropout:

– 115mV (typical) (legacy chip) at 3.0A

– 120mV (typical) (new chip) at 3.0A

• Stable with any or no output capacitor (legacy

chip)

• Stable with any output capacitor ≥2.2μF (new chip)

• Power-good (PG) output allows supply monitoring

or provides a sequencing signal for other supplies

• Packages:

– 5mm × 5mm × 1mm VQFN (RGW)

– 3.5mm × 3.5mm VQFN (RGR), and DDPAK-7

(legacy chip only)

2 Applications

• Network attached storage - enterprise

• Rack servers

• Network interface cards (NIC)

• Merchant network and server PSU

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.
