Description

  • Pololu 1.4-7V, 3.8A Fine-Adjust Step-Down Voltage Regulator W/ Adjustable Low-Voltage Cutoff D30V33MALCMA
  • Converts 3V-45V input to 1.4V-7V output
  • Delivers 3A-5A continuous current
  • Achieves 80%-95% efficiency
  • Includes precision 11-turn potentiometer
  • Compact size with mounting holes

The Pololu 1.4-7V, 3.8A Fine-Adjust Step-Down Voltage Regulator W/ Adjustable Low-Voltage Cutoff D30V33MALCMA is a versatile voltage regulator designed to efficiently convert a wide range of input voltages from 3 V to 45 V into a stable output voltage between 1.4 V and 7 V. This regulator is capable of delivering a continuous output current typically ranging from 3 A to 5 A, depending on operating conditions. It is engineered for high efficiency, achieving typical efficiency levels between 80% and 95%, and incorporates several protective features to ensure reliable operation.

The device includes a precision 11-turn potentiometer, allowing for fine adjustments of both the output voltage and the low-voltage cutoff threshold. It is equipped with a soft-start function, under-voltage lockout protection, and integrated reverse-voltage protection up to 40 V. Additionally, the regulator features a power-save mode to enhance efficiency under light loads and a "power good" output to signal when the output voltage is not adequately maintained.

Compact in design, the regulator measures 0.9" × 1.2" × 0.3" and includes mounting holes for secure installation. It also supports through-hole connections for headers and terminal blocks, facilitating easy integration into various applications. Note: Ensure proper handling to avoid exposure to conditions exceeding the specified voltage and current limits.
