SE79XXA
Elektronische Bauelemente
3-Terminal
Negative
Voltage Regulator
Description
The SE79XXA series of fixed-voltage monolithic intergrated-
circuit voltage regulators designed to complement Series
SE78XXA in a wide range of applications. These applications
include on-card regulation for elimination of noise and
distribution problems associated with single-point regulation.
Each of these regulators can deliver up to 1.5A of output
current. The internal current limiting and thermal shutdown
features of these regulators make them essentially immune
to overload. In addition to use as fixed-voltage regulators,
thesedevices can be used with external components to
obtain adjustable output voltage and current and also as the
power pass element in precision regulators.
Features
*-5V,-6V,-8V,-9V,-10V,-12V,-15V,-18V,-24V Output Voltage Available
*Output Transistor Safe-Area Compensation
*No External Components
*Internal Thermal Overload Protection
*Internal Short-Circuit Current Limiting
*High
Power Dissipation Capability
