The compact (0.4″ × 0.5″) D24V3F12 switching step-down (or buck) voltage regulator takes an input voltage between 14.5 V and 42 V and efficiently reduces it to 12 V while allowing for a maximum output current of 300 mA. The pins have a 0.1″ spacing, making this board compatible with standard solderless breadboards and perfboards.

Overview

These voltage regulators generate lower output voltages from input voltages as high as 42 V. They are switching regulators (also called switched-mode power supplies (SMPS) or DC-to-DC converters) and have a typical efficiency between 80% to 90%, which is much more efficient than linear voltage regulators, especially when the difference between the input and output voltage is large.

This regulator’s thermal shutdown prevents damage from overheating, but it does not have short-circuit or reverse-polarity protection!

Features

  • Input voltage: [output voltage + dropout voltage] to 42 V (see below for more information on dropout voltage)
  • Fixed 3.3 V, 5 V, 9 V, or 12 V output (depending on regulator version) with 4% accuracy
  • Maximum output current: 300 mA or 600 mA (depending on regulator version)
  • 1.25 MHz switching frequency
  • 2 mA typical no-load quiescent current (20 μA typical quiescent current with SHDN = LOW)
  • Integrated over-temperature and over-current shutoff
  • Small size: 0.5″ × 0.4″ × 0.1″ (13 mm × 10 mm × 3 mm)
