LM1117T-3.3 Voltage Regulator – 3.3V LDO Linear Regulator, TO-220 Package, 800 mA Output

The LM1117T-3.3 is a fixed low dropout (LDO) linear voltage regulator designed to provide a stable 3.3V output with up to 800 mA of current. Housed in a TO-220 package, it is ideal for use in power supply designs for embedded systems, microcontrollers, sensors, and logic-level electronics. This regulator features a low dropout voltage of typically 1.1 V, allowing it to operate efficiently even with minimal voltage overhead. Integrated short-circuit and thermal protection ensures reliable operation in a wide range of applications.

Key Features:

• Fixed 3.3V output voltage with ±1% accuracy
• Delivers up to 800 mA of output current
• Low dropout voltage: 1.1 V typical at full load
• Built-in thermal and short-circuit protection
• Standard TO-220 package for easy heatsinking
• Ideal for logic-level voltage regulation from 5V or 4.5V supplies
