3-TERMINAL NEGATIVE VOLTAGE REGULATOR
Description
The H7912_E series of three-terminal negative regulators are avail-
TO-220
able in the TO-220AB package. They can provide local on-card
regulation, eliminating the distribution problems associated with single point regulation;
furthermore, having the same voltage options as the H7912_E positive standard series, they are
particularly suited for split power supplies. If adequate heat sinking is provided, the H7912_E
series can deliver an output current in excess of 1A although designed primarily as fixed voltage
regulators, these devices can be used with external components to obtain adjustable voltage and
currents.

Note:
By pass Capacitors are
recommended for optimum stability
and transient response and should
be locate as close as possible to the
regulator.
