DD38LOSA 5V DC-DC / LDO Step-Down Regulator Module

DD38LOSA 5V DC-DC / LDO Step-Down Regulator Module

The DD38LOSA 5V regulator module combines a DC-DC switching regulator and LDO in a single compact module, providing a stable 5V output from a wide input range of 5.5V to 18V. Higher efficiency than a pure LDO — ideal for powering Arduino and 5V modules from 9V, 12V, or higher DC supplies with minimal heat.

Key Specifications

• IC: DD38LOSA | Input: 5.5–18V | Output: 5V
• Max current: 600mA | Efficiency: high (DC-DC switching)
• Header: 2.54mm breadboard compatible
• Compliance: RoHS compliant

Why Choose This?

• ✅ Wide input range (5.5–18V) — works from 9V, 12V, and higher DC supplies
• ✅ High efficiency — less heat than LDO regulators at high input voltages
• ✅ Stable 5V — clean output for Arduino and 5V sensor modules
• ✅ Compact module — minimal footprint for embedded power supply

Typical Applications

• 12V to 5V efficient step-down for Arduino projects
• Vehicle 12V to 5V power supply for embedded systems
• Industrial 12V/24V to 5V sensor power supply
• Battery-powered 5V project power rail
