PJ7900 Series 3-Terminal Negative Output Voltage Regulators T hese voltage regulators are intended as complements to Available in fixed output voltage options from -5.0 to - the popular PJ7900 Series devices. These negative 24 volts, these regulators employ current limiting, thermal regulators are available in the same seven-voltage options as shutdown, and safe-area compensation--making them the PJ7900 devices. In addition, one extra voltage option remarkably rugged under most operating conditions. With commonly employed in MECL systems is also available in adequate heatsinking they can deliver output currents in the negative PJ7900 Series. excess of 1 ampere.

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. 2-9 2002/10.rev.A mA μV dB V A mV/ ℃ PJ7900 Series 3-Terminal Negative Output Voltage Regulators • PJ7906 ELECTRICAL CHARACTERISTICS (Vin=-11V, Iout=500mA, Cin=2μF, Cout=1μF; Tj=0℃ to 125℃, unless otherwise specified.)
