These buck (step-down) 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 is available with a fixed 3.3 V, 5 V, 9 V, or 12 V output, and two versions are available for each voltage, one with a 300 mA maximum output current (D24V3Fx) and one with a 600 mA maximum output current (D24V6Fx)
The regulator has short-circuit protection, and thermal shutdown prevents damage from overheating. The board does not have reverse-voltage protection.
If you need more output current, consider our D15V35F5S3 and D15V70F5S3 3.3V/5V step-down voltage regulators, which can typically deliver a continuous 3.5 A and 7 A, respectively.

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)
  • 550 kHz 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)
Dimensions:
  • Size: 0.4″ × 0.5″ × 0.1″1
  • Weight: 0.5 g1
Specifications:
  • Minimum operating voltage: 10.5 V2
  • Maximum operating voltage: 42 V
  • Maximum output current: 300 mA
  • Output voltage: 9 V
  • Reverse voltage protection?: N
  • Maximum quiescent current: 2 mA3
Notes:
  • 1. Without included optional headers.
  • 2. For small loads; input voltage must be at least 11 V to get 250 mA and 12.5 V to get the full 300 output.
  • 3. While enabled (SHDN = HIGH) with no load. Current draw is approximately 20 µA when SHDN = LOW.
