TPS74901 - 3-A Low Dropout Linear Regulator

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.

Features

  • 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 Other Supplies.
  • 2% Accuracy Over Line, Load, and Temperature.
  • Adjustable Start-Up In-Rush Control.
  • VBIAS Permits Low VIN Operation With Good Transient Response.
  • Stable with Any Output Capacitor ≥ 2.2 µF.
