Description

  • Pololu 1.4-7V, 3.8A Fine-Adjust Step-Down Voltage Regulator D30V33MAL
  • Converts 3-45V input to 1.4-7V output
  • Supports up to 3.8A continuous current
  • Features high efficiency up to 95%
  • Includes reverse voltage protection
  • Offers compact 0.9"×1.2"×0.3" design

The Pololu 1.4-7V, 3.8A Fine-Adjust Step-Down Voltage Regulator D30V33MAL is a versatile device designed to convert a wide range of input voltages into a stable output voltage between 1.4 V and 7 V. It supports a maximum continuous output current of 3.8 A and features a precision-adjustable output via an 11-turn potentiometer.

This regulator is engineered for high efficiency, offering protection against reverse voltage, over-current, short-circuit, and over-temperature conditions. It includes a soft-start feature to manage inrush current and a "power good" output to signal when the output voltage is insufficient. The compact design facilitates easy integration into various applications.
