DESCRIPTION

The S79L05 series of three-terminal negative regulators

are available in the TO-92 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 SM79L05

positive standard series, they are particularly suited for

split power supplies. If adequate heat sinking is provided,

the S79Lxx 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.

APPLICATION

Note:

Bypass capacitors are recommended for optimum stability and transient

response and should be located as close as Possible to the regulators
