L7912 Voltage Regulator -12VDC @ -1.5A - (AD1251)

Description:

The L7900 series of three-terminal negative regulators is available in TO-220. These regulators can provide on-card regulation, eliminating the distribution problems associated with single-point regulation; moreover, having the same voltage option as the standard positive L7800 series, they are particularly suitable for split power supplies.
