SE7905
3-Terminal Negative Voltage Regulator
RoHS Compliant Product
A suffix of “-C” specifies halogen or lead -free
DESCRIPTION
The SE7905 of fixed-voltage monolithic integrated-
circuit voltage regulators designed to complement.
The SE7905 in a wide range of applications. These
applications include on-card regulation for elimination of
noise and distribution problems associated with single-point
regulation. 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,
these devices can be used with external components to
obtain adjustable output voltage and current and also as
the power pass element in precision regulators.
FEATURES
1.5A Output Current
Internal Short-Circuit Current Limiting
Output Transistor Safe-Area Compensation
No External Components
