Description
The AMS1086CD-3.3 is a low-dropout (LDO) voltage regulator that provides a fixed 3.3V output with a maximum current of 1.5A. It features a low dropout voltage (typically 1.3V at full load), making it suitable for applications with tight input-output differentials.
Key characteristics:
- Input voltage range: 4.75V to 12V
- Low quiescent current (~10mA)
- Thermal overload & short-circuit protection
- TO-252 (DPAK) package for efficient heat dissipation
Common uses include powering microcontrollers, sensors, and digital circuits where stable 3.3V supply is required. Its compact design and robust protection features make it ideal for embedded systems and portable electronics.
For optimal performance, ensure proper heat sinking at higher loads and use input/output capacitors (typically 10µF) for stability.
