LD1117 / LM1117 - 3.3V LDO Voltage regulator 1.3A TO220

The LD1117/LM1117 is a fixed 3.3V low-dropout (LDO) voltage regulator capable of delivering up to 1.3A of output current. Housed in a standard TO-220 package, it is ideal for stepping down higher input voltages (such as 5V or 12V) to a stable 3.3V supply for Arduino microcontrollers, Raspberry Pi modules, and other sensitive electronic circuits.

Specifications

• Output Voltage: 3.3V fixed
• Max Output Current: 1.3A
• Type: Low Dropout (LDO) Regulator
• Package: TO-220
• Minimum Input Voltage: approx. 4.5V (depending on load current)

Note: A heat sink may be required for high currents or large input-to-output voltage differences.
