Design TPS74901
SBVS082I – JUNE 2007 – REVISED MAY 2016 TPS74901 3-A Low Dropout Linear Regulator With Programmable Soft-Start
1 Features 3 Description The TPS74901 low-dropout (LDO) linear regulator
provides an easy-to-use, robust power management
solution for a wide variety of applications. Userprogrammable soft-start minimizes stress on the input
power source by reducing capacitive inrush current
during start-up. The soft-start is monotonic and wellsuited for powering many different types of
processors and ASICs. The enable input and powergood output allow easy sequencing with external
regulators. This complete flexibility permits the user to
configure a solution that meets the sequencing
requirements of FPGAs, DSPs, and other
applications with special start-up requirements. 1 VOUT Range: 0.8 V to 3.6 V
Ultralow VIN Range: 0.8 V to 5.5 V
VBIAS Range: 2.7 V to 5.5 V
Low Dropout: 120 mV (Typical) at 3 A
Power-Good (PG) Output Allows Supply
Monitoring or Provides a Sequencing Signal for …
