TPS7A19 - Low-Dropout Voltage Regulator

General Description

The TPS7A19 is a low-dropout linear regulator (LDO) with a wide input voltage (VIN) range up to 40 V, capable of sourcing high output current (IOUT) up to 450 mA.

This voltage regulator is ideal for generating a low-voltage supply from wide input-voltage rails.

Key Features

  • 1 Wide Input Voltage Range: 4 V to 40 V.
  • Adjustable Output Voltage: 1.5 V to 18 V.
  • Output Current: 450 mA.
  • Low Quiescent Current (IQ): 15 µA.
  • Low Dropout Voltage: 450 mV (max) at 400 mA.
  • Power Good with Programmable Delay.
  • Thermal Shutdown and Overcurrent Protection.
  • Stable with Ceramic Output Capacitors:.
  • 10 µF to 500 µF for VOUT ≥ 2.5 V.
  • 22 µF to 500 µF for VOUT < 2.5 V.
  • Operating Temperature:.
