Description
It's an LM1117 800-mA Low-Dropout Linear Regulator. The LM1117 is a popular low-dropout linear regulator (LDO) manufactured by Texas Instruments. It is designed to provide a regulated output voltage with low dropout voltage, which means it can maintain a stable output even when the input voltage is close to the desired output voltage. The LM1117 can provide a maximum output current of 800 mA. This means it can supply up to 800 mA of current to the load while maintaining a regulated output voltage. The dropout voltage is the minimum voltage difference between the input and output voltages required for the regulator to operate correctly. The LM1117 has a low dropout voltage, typically around 1.2V at full load. The LM1117 can accept an input voltage in the range of 4.75V to 15V. It is important to ensure that the input voltage does not exceed the maximum specified voltage to avoid damaging the regulator. The LM1117 is available in various versions, each providing a different fixed output voltage. Common output voltage options include 3.3V, 5V, and adjustable versions that allow you to set the output voltage using external resistors.
