PJ7900 Series
3-Terminal Negative Output Voltage Regulators
T
hese voltage regulators are intended as complements to
the popular PJ7900 Series devices. These negative
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.
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.

means that the test should be carried out with the test time so short (within 10mS), that the drift in

STANDARD APPLICATION
A common ground is required between the input and the output voltages. The input voltage must remain typically 2.0 V
more negative even during the high point on the input ripple voltage.
XX = these two digits of the type number indicate voltage.
* = Cin is required if regulator is located an appreciable distance from power supply filter.
** = Co improves stability and transient response.
