The LM1117T-3.3 Voltage Regulator is provided in a pack of one, featuring a low-dropout (LDO) linear voltage regulator in a TO-220 package. It delivers a fixed output voltage of 3.3V with a maximum output current of 1.2A, designed to regulate input voltages ranging from 4.5V to 15V.
The regulator has a typical dropout voltage of 1.2V at 800mA, requiring an input voltage at least 1.2V above the output for proper regulation (minimum 4.5V).
It is housed in a 3-pin TO-220 package measuring approximately 10mm x 4.5mm x 9.4mm, with a tab for heatsink mounting to manage thermal dissipation.
The LM1117T-3.3 includes internal protection features such as thermal shutdown and current limiting, ensuring safe operation under typical conditions. It operates within a temperature range of 0°C to +125°C and requires a minimum 10µF tantalum capacitor at the output to improve transient response and stability.
This component is commonly used in circuits requiring a stable 3.3V supply, such as those powering microcontrollers or sensors.
Key Features:
- Output Voltage: 3.3V – Provides a stable 3.3V supply for low-voltage circuits.
- Output Current: Up to 1.2A – Suitable for powering small devices, though continuous use above 800mA requires a heatsink.
