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;furthe-
more, 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.
