Pinout
1. Pin 1 (Input): This is the input pin where the unregulated voltage is supplied. It is important to ensure that the input voltage is within the specified range for proper operation.
2. Pin 2 (Ground): This pin is connected to the system ground. It serves as a reference point for the input and output voltages.
3. Pin 3 (Output): This pin provides the regulated output voltage, which, in the case of the MC78LC33HT1G, is fixed at 3.3 volts. The output is maintained at this voltage level as long as the input voltage is above the dropout voltage and within the specified input voltage range.
This LDO regulator is used in applications where a stable and precise 3.3V output is required from a higher input voltage, with the advantages of low dropout and low quiescent current.
