3-TERMINAL NEGATIVE VOLTAGE REGULATOR

Description

The H7912_E series of three-terminal negative regulators are avail-

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.

By pass Capacitors are

recommended for optimum stability

and transient response and should

be locate as close as possible to the

regulator.
