T
hese voltage regulators are intended as complements to
the popular PJ7900 Series devices. These negative
regulators are available in the same seven-voltage options as
the PJ7900 devices. In addition, one extra voltage option
commonly employed in MECL systems is also available in
the negative PJ7900 Series.
Available in fixed output voltage options from -5.0 to -
24 volts, these regulators employ current limiting, thermal
shutdown, and safe-area compensation--making them
remarkably rugged under most operating conditions. With
adequate heatsinking they can deliver output currents in
excess of 1 ampere.
Output Current up to 1 Ampere
