Description

The LM1117T-3.3 is a low-dropout voltage regulator designed to provide a stable 3.3V output voltage. It is part of the LM1117 series, which offers various fixed and adjustable output voltages. The "T" in the part number indicates the TO-220 package, which is commonly used for its ability to dissipate heat efficiently. The LM1117T-3.3 is known for its low dropout voltage of approximately 1.2V at full load of 800mA, making it suitable for applications where the input voltage is not much higher than the output voltage.
Key features include over-temperature and over-current protection, ensuring reliability and durability in various applications. It also boasts a typical output tolerance of ±1% and a quiescent current of around 5mA. The regulator is widely used in electronic circuits where a stable 3.3V supply is required, such as in microcontrollers, microprocessors, and other digital systems. Its ease of use and robust performance make it a popular choice for both hobbyist and professional applications.

Features

The LM1117T-3.3 is a voltage regulator with a fixed output of 3.3 volts. Key features include:
1. Output Voltage: 3.3V with a tolerance of ±1%.
2. Output Current: Can deliver up to 800 mA.
3. Dropout Voltage: Low dropout voltage, typically around 1.2V at full load.
4. Thermal Protection: Includes thermal shutdown to prevent overheating.
5. Current Limiting: Built-in current limiting for overload protection.
6. Stability: Requires external capacitors for stability, typically a 10μF tantalum or aluminum electrolytic output capacitor.
7. Operating Temperature: Supports a range from 0°C to +125°C.
8. Package: Available in a TO-220 package for easy mounting and heat dissipation.
These features make the LM1117T-3.3 suitable for applications that need a reliable and efficient fixed voltage supply, especially in systems with varying input voltages or where space is limited.

Package

The LM1117T-3.3 is a low-dropout linear voltage regulator with a fixed output of 3.3 volts. It is commonly packaged in a TO-220 package, which is a through-hole type known for good heat dissipation, making it suitable for power applications.

Pinout

The LM1117T-3.3 is a voltage regulator with a fixed output voltage of 3.3V. It typically comes in a TO-220 package and has three pins. Here are the pin functions:
1. Pin 1 (ADJ/GND): In the fixed version like the LM1117T-3.3, this pin serves as the ground. In adjustable versions of the LM1117, this pin is used for adjusting the output voltage.
2. Pin 2 (VOUT): This is the output pin, which provides the regulated 3.3V output.
3. Pin 3 (VIN): This pin is connected to the input voltage source. It requires an input voltage higher than 3.3V to regulate the output correctly.
The LM1117T-3.3 is designed for applications requiring a fixed output voltage with a maximum output current of up to 800mA. It's commonly used in power supply circuits for microcontrollers and other digital logic components.
