AMS1085CM-3.3

The AMS1085CM-3.3 is a low-dropout (LDO) linear voltage regulator designed to provide a fixed 3.3V output with a maximum input voltage of 18V. It delivers up to 1A of current with a typical dropout voltage of 1.3V at full load.
Key features include:
- Low dropout voltage for efficient regulation.
- High accuracy (±2% output tolerance).
- Thermal shutdown and current limiting for protection.
- Low quiescent current (~10mA).
Applications include powering microcontrollers, sensors, and other low-voltage circuits in industrial, automotive, and consumer electronics. The TO-252 (DPAK) package ensures good thermal performance.
For stable operation, a 10μF output capacitor is recommended. Always refer to the datasheet for detailed specifications.
