Function : -12V, Voltage Regulator
Package : TO-220, TO220FP, D2PAK Type
Manufactures : STMicroelectronics, Inchange Semiconductor
-12V, Negative Voltage Regulator
The L79 series of three-terminal negative regulators is available in TO-220, TO-220FP and D²PAK packages and several fixed output voltages, making it useful in a wide range of applications.
These regulators can provide local on-card regulation, eliminating the distribution
problems associated with single point regulation; furthermore, having the same voltage option as the L78 positive standard series, they are particularly suited for split power supplies. If adequate heat sinking is provided, they can deliver over 1.5 A output current.
Although designed primarily as fixed voltage regulators, these devices can be used
with external components to obtain adjustable voltages and currents.
1. Output current in excess of 1.5A
2. Output voltage of -12V
3. Internal thermal overload protection
4. Output transition Safe-Area compensation
5. Minimum Lot-to-Lot variations for robust device performance and reliable operation
