This series fixed-voltage monolithicintegrated-circuit voltage regulators designed wide range applications. These applications include on-card regulation elimination noise distribution problems associated with single-point regulation. addition, they used with power-pass elements make high-current voltage regulators. Each these regulators deliver to100 output current. internal limiting termal shutdown features these regulators make them essentially immune overload. When used replacement Zener diode-resistor combination, effective improvement output impedance obtained together with lower-bias current.
