Keep Output Voltage Steady with 5V 1A Step-Up/Step-Down Voltage Regulator S13V10F5

The 5V 1A Step-Up/Step-Down Voltage Regulator S13V10F5 keeps output voltage steady even when the input moves above or below the target level.

That makes it a good choice for battery systems, mobile robots, and field devices that need dependable power across a wide input range.

Important: Choose a regulator based on your full input-voltage range, startup current, thermal limits, and required headroom. Real output current depends on input voltage, airflow, and temperature.

Why you'll love it

  • 5V microcontrollers & sensors powered from batteries (1S Li-ion, AA packs, 2S/3S with sag)
  • Projects that need stable 5V across discharge curves
  • Compact builds where linear regulators would get too hot
  • Quick prototyping with breadboards and perfboards
  • Buck-boost convenience: stable 5V whether your input is higher or lower than 5V
  • Efficient: typically ~85–95% depending on VIN and load (better battery life, less heat)

What you can build

Useful for battery-powered devices, mobile robots, field instruments, and portable systems where the input can move above and below the target output.

Frequently Asked Questions

Can I power a microcontroller with this?
Yes, if the regulator’s output voltage and current match your controller and all attached loads.
Will it run cool at full load?
It depends on input voltage, airflow, and load current. Check thermal limits in the official Pololu resources.
Is this better than a linear regulator?
For many builds, yes. Switching regulators are usually more efficient and waste less heat.
