LM1117T-3.3 voltage stabilizing module

The LM1117 voltage stabilizing circuit is a commonly used linear voltage stabilizing circuit, which can stably output the input voltage to a fixed voltage. In electronic equipment, the voltage stabilizing circuit is very important because it can ensure the stability of the working voltage of each component in the circuit, thereby ensuring the normal operation of the circuit. The working principle of the LM1117 voltage stabilizing circuit is based on the principle of a three-terminal voltage regulator. It consists of an input terminal, an output terminal and a ground terminal. The input terminal accepts the voltage from the power supply, and the output terminal outputs a stable voltage. In a voltage stabilizing circuit, the input voltage passes through a capacitor filter to remove noise and clutter from the power supply. The voltage then goes to a reference voltage circuit in the voltage regulator chip, which stabilizes the voltage at a fixed value. Next, the voltage passes through an error amplifier, which compares the reference voltage to the output voltage and amplifies the error signal. Finally, the error signal passes through a power amplifier to control the output voltage to keep the output voltage stable. The LM1117 voltage regulator circuit has many advantages. First, it has lower output noise and temperature drift and can operate over a wide temperature range. Secondly, it has a high output current capability that can meet the needs of most applications. In addition, it has short circuit protection and overheating protection to protect the circuit from damage.
