SM79L12

SM79L12 Elektronische Bauelemente 3-Terminal Negative Voltage Regulator Description The SM79L12 series of three-terminal negative regulators are available in the SOT-89 package. They can provide local on card-regulation, eliminating the distribution problems associated with single point regulation;furthemore, having the same voltage options as the SM79L12 positive standard series, they are particularly suited for split power supplies. If adequate heat sinking is provided, the SM79L12 series can deliver an output current in excess of 100mA although designed primarily as fixed voltage regulators, these devices can be used with external components to obtain adjustable voltage and currents.
