Fairchild Semiconductors Semiconductors Linear 1.C.s - Voltage Regulators LM304 Negative Voltage Regulator GENERAL DESCRIPTION The LM304 precision negative voltage regulator is constructed using the Fairchild Planar epitaxial process, This device can be programmed by a single external resistor to supply any voltage from OV to 30V from a single unregulated supply. When used with a separate floating bias supply, the 304 can provide 0.01% regulation with the output voltage limited only by the breakdown of external pass transistors. _ FEATURES imvV regulation with full load. 0.01%/V line regulation. O0.2mV/V ripple rejection. 0.3% temperature stability over full temperature range. REFERENCE TABLE CONNECTION DIAGRAM TOP VIEW See outline drawing No. 98 for dimensions.

They can also provide 0.01 per cent regulation in circuits using a separate, floating bias supply, where the output voltage is limited only by the breakdown of external pass transistors. Although designed primarily as tinear, series regulators, the circuits can be used as switching regulators, current regulators or ina number of other control applications. FEATURES 1 mV regulation no load to full load 0.01%/V line regulation : 6.2 mV/V ripple rejection 0.3% temperature stability over military temperature range The LM104 Series are complements of the LM100 Series positive regulators, intended for systems requiring regulated negative voltages which have a common ground with the unregulated supply. By themselves, they can deliver output currents to 25 mA, but external transistors can be added to get any desired current.. The output voltage is set by external resistors, and either constant or foldback current limiting is made available. CONNECTION.
