AMS1117-ADJ** is a low dropout voltage regulator manufactured by **Advanced Monolithic Systems (AMS)**.

The AMS1117-ADJ is a low dropout voltage regulator manufactured by Advanced Monolithic Systems (AMS). Below are its key specifications, descriptions, and features:

Specifications:

  • Output Voltage: Adjustable (1.25V to 13.8V)
  • Output Current: Up to 1A
  • Dropout Voltage: 1.2V (typical at full load)
  • Input Voltage Range: Up to 15V
  • Line Regulation: 0.2% (typical)
  • Load Regulation: 0.4% (typical)
  • Operating Temperature Range: -40°C to +125°C
  • Package Options: TO-252 (DPAK), TO-220, SOT-223

Descriptions:

  • The AMS1117-ADJ is an adjustable linear regulator with a low dropout voltage, making it suitable for battery-powered and low-voltage applications.
  • It requires only two external resistors to set the output voltage.
  • Includes built-in current limiting and thermal shutdown protection.

Features:

  • Adjustable Output: Set via external resistors (R1 and R2).
  • Low Dropout Voltage: Ensures efficient regulation even with small input-output differentials.
  • High Accuracy: Tight output voltage tolerance.
  • Thermal & Current Protection: Prevents damage from overheating or excessive current.
  • Stable with Low-ESR Capacitors: Works reliably with ceramic or tantalum capacitors.

This regulator is commonly used in power supplies, embedded systems, and portable electronics. For exact performance values, refer to the official AMS1117-ADJ datasheet.
