This series fixed-negative-voltage monolithic integrated-circuit voltage regulators designed complement Series MIK7800 wide range applications. These applications include on-card regulation elimination noise distribution problems associated with single point regulation. Each these regulators deliver amperes output current. internal current limiting thermal shutdown features these regulators make them essentially immune overload. addition fixedvoltage regulators, these devices used with external components obtain adjustable output voltages current also power pass element precision regulators.
