Description
These regulators employ internal current-limiting and thermal-shutdown, making
them essentially indestructible. They can deliver up to 100mA output current.
Features
•
Maximum Output Current of 100mA (T
C
=25°C)
•
Internal Short-Circuit Current Limiting
•
Internal Thermal Overload Protection
