Steady 3.3 V from up to 36 V on a board smaller than a postage stamp
Pololu D24V7F3 is a synchronous step-down regulator that turns an input voltage of 4 to 36 V into a steady 3.3 V and delivers up to 600 mA. The board measures 8.6 x 13.7 mm and weighs 0.5 g, so it fits in a small enclosure, and the three pins at 2.54 mm pitch fit a breadboard.
You can power microcontrollers and 3.3 V modules such as the ESP32, Raspberry Pi Pico or sensors with 3.3 V logic from it. The 600 mA current is available at any combination of input and output voltage, and with no load the regulator draws less than 0.01 mA, so it works well in battery-powered devices.

A good choice for you?
A good choice if:
- you need a steady 3.3 V from a battery, rechargeable battery or power supply up to 36 V
- your circuit draws up to 600 mA
- small size and low idle current draw matter
Consider another option if:
- you need more current: see the Pololu D24V10F3 step-down regulator (3.3 V, 1 A)
- you want to protect your circuit against reversed power connection: add the Pololu 4-75 V 8 A protection module

Frequently asked questions
Can I power the regulator from a 1S Li-Ion battery?
A single Li-Ion cell has at most about 4.2 V and the regulator needs at least 4 V, so it will only work with a charged cell. For powering from a single cell, a step-up/step-down regulator is a better choice.
Will the regulator survive a short circuit on the output?
Yes, it has short-circuit and thermal protection. However, it does not protect against reversed power connection at the input.
Are pins included?
No. The regulator is supplied without header strips, but you can solder on straight pins, right-angle pins or wires directly.
