L7905 is a member of the L79xx series of voltage regulators, designed to provide a fixed -5V output (negative voltage).
Output Voltage: -5V (regulated, negative voltage)
Input Voltage: Typically -7V to -35V DC (the input voltage must be more negative than the output by at least the dropout voltage).
Output Current: Up to 1A (depends on input voltage, load current, and heat dissipation).
Output Tolerance: Typically ±2% (depending on the manufacturer).
Regulation Type: Linear voltage regulator (provides stable output voltage despite variations in input voltage and load current within specified limits).
