3-Terminal Negative Output Voltage Regulators

1-8

2003/06.rev.B

hese voltage regulators are intended as complements to

the popular PJ7900B Series devices. These negative

regulators are available in the same seven-voltage options as

the PJ7900B Series devices. In addition, one extra voltage

option commonly employed in MECL systems is also

available in the negative PJ7900B 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
· No External Components Required
· Internal Thermal Overload Protection
· Internal Short-Circuit Current Limiting
· Output Transistor Safe-Area Compensation

Available in 4% Voltage Tolerance

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.
