description
This series fixed negative-voltage integrated-circuit SOT-89 voltage regulators designed wide range COMMON INPUT OUTPUT 79L05CPK applications. These include on-card regulation elimination noise distribution problems associated with single-point regulation. addition, they used control series pass elements make high-current voltage-regulator circuits. these regulators deliver output current. internal current-limiting thermal-shutdown features make them essentially immune overload. When used replacement zener-diode resistor combination, these devices provide fective improvement output impedance orders magnitude, with lower bias current.
