L7815 is part of the L78xx series of voltage regulator ICs, which are designed to provide a fixed positive output voltage. The L7815 specifically provides a 15V output.
Output Voltage: 15V (regulated)Input Voltage: Typically 18V to 35V DC (minimum input voltage should be higher than 15V by at least the dropout voltage).
Output Current: Up to 1A (depends on input voltage, output current, and heat dissipation).
Output Tolerance: Typically ±2% (depending on manufacturer).
Regulation Type: Linear regulator (provides stable output voltage despite variations in input voltage and load current within specified limits).
Key Parameters:
Dropout Voltage: Typically around 2V (the input voltage must be at least 17V to maintain the 15V output under full load conditions).
Thermal Shutdown: Includes internal thermal shutdown protection to prevent damage from excessive heat.
Short Circuit Protection: Has short-circuit protection to avoid damage in case of a short on the output.
