Yes, there are several voltage regulators and LDOs that can take an input range of 5V to 12V and output a stable 5V. The choice depends on your current requirements and how much efficiency or heat tolerance you need.
✅ Common Options:
🔹 1. Linear Regulators (e.g., 7805, AMS1117-5.0)
7805: Classic linear regulator, input up to 35V.
Easy to use, but inefficient—dissipates extra voltage as heat.
Good for low-power applications.
AMS1117-5.0: LDO with dropout ~1.1V.
Needs at least ~6.1V input to maintain stable 5V output.
Not suitable if your input drops to near 5V.
🔧 Note: Linear regulators get hot when stepping down from 12V to 5V at high current—add a heatsink if needed.
🔹 2. Switching Regulators (Buck Converters)
Much more efficient, especially if your input varies from 12V down to 5V.
Examples:
LM2596 (DC-DC buck module, very common)
MP1584, XL4015, TPS5430
Accept wide input (up to 30V depending on model), and maintain stable 5V output with high efficiency (80–90%).
✅ Great for powering microcontrollers, LED strips, sensors, etc.
🔹 3. LDO with Wide Input Support
If you need a proper LDO with better efficiency than a 7805:
LT1763, MIC29302, or LD1117 can be good choices depending on your current and dropout needs.
🔍 Recommendation:
If your input drops close to 5V, use a buck-boost converter or LDO with ultra-low dropout.
For most general use (like Arduino or Raspberry Pi), a buck converter is the most practical and efficient.
