Pololu 5V 600mA Step-Down Voltage Regulator (D36V6F5) 

Power your 5V electronics from almost anything. The Pololu D36V6F5  is a tiny buck (step-down) switching regulator that takes 5.2V–50V input and outputs a stable 5V (±4% accuracy), with up to 600mA maximum output current (thermal-dependent). Because it’s a switching regulator, it’s typically far more efficient than a linear 7805—especially when dropping from higher voltages like 12V/24V down to 5V. :contentReference[oaicite:0]{index=0}

  • Wide input range: 5.2V to 50V (minimum input depends on dropout; see notes below).
  • Low-power capable: enable pin can put the board into a low-power state drawing <2µA (typ.).
  • Low quiescent current: <0.1mA while enabled with no load (typical graphs available on Pololu).
  • Protection features: over-current/short-circuit protection and thermal shutdown.
  • Super small: 0.5" × 0.4" × 0.1" (13×10×3mm), ~0.5g. 

*Actual continuous output current depends on input voltage, airflow, and thermal conditions (see Pololu’s current graphs).

Important: This board does not have reverse-voltage protection. Double-check polarity before powering. 

Why/Benefits

Efficient 5V from higher voltages
  • Great for 12V/24V systems feeding 5V sensors, MCUs, and modules 
  • Less heat than linear regulators when dropping large voltage differences 
  • Compact footprint for tight builds
Battery & low-power friendly
  • Enable pin supports ultra-low sleep current (<2µA typical) 
  • Low quiescent current while enabled (<0.1mA) 
  • Good for always-on projects that still need long battery life

Pinout & power notes

  • VIN: connect your input supply (5.2–50V). 
  • VOUT: regulated 5V output.
  • GND: common ground between input and load.
  • EN (Enable): use to switch the regulator on/off or enter ultra-low-power mode (<2µA typical). 

Dropout reminder: the minimum input voltage depends on dropout; for a stable 5V output, ensure your VIN stays sufficiently above 5V under load.

FAQ

  • Can I use this to power an ESP32/Arduino from 12V?
    Yes—12V is within the 5.2–50V input range. Just ensure your total 5V load stays within the regulator’s current/thermal limits.
  • Does it have reverse-polarity protection?
    No. Use correct polarity and consider adding an external protection diode or fuse for safety. 
  • How do I make it ultra low power?
    Use the enable pin to disable the regulator; Pololu notes it can draw less than 2µA typical in the low-power state.
