LM104 LM204 LM304 Negative Regulator March 1989 LM104 LM204 LM304 Negative Regulator General Description The LM104 series are precision voltage regulators which can be programmed by a single external resistor to supply any voltage from 40V down to zero while operating from a single unregulated supply They can also provide 0 01-percent 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 linear series regulators the circuits can be used as switching regulators current regulators or in a number of other control applications Typical performance characteristics are Y Subsurface zener reference Y 1 mV regulation no load to full load Y 0 01% V line regulation Y 0 2 mV V ripple rejection Y 0 3% temperature stability over military temperature range The LM104 series is the complement of the LM105 positive regulator 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 The LM104 is specified for operation over the b55 C to a 125 C military temperature range The LM204 is specified for operation over the b25 C to a 85 C temperature range The LM304 is specified for operation from 0 C to a 70 C Schematic Diagram TL H 7754 – 1 C1995 National Semiconductor

temperatures devices in the H10C package must be derated based on a thermal resistance of 150 C W junction to ambient or 45 C W junction to case Note 2 These specifications apply for junction temperatures between b 55 C and 150 C (between b 25 C and 100 C for the LM204 and 0 C to a 85 C for the LM304) and for input and output voltages within the ranges given unless otherwise specified The load and line regulation specifications are for constant junction temperature Temperature drift effects must be taken into account separately when the unit is operating under conditions of high dissipation Note 3 When external booster transistors are used the minimum output-input voltage differential is increased in the worst case by approximately 1V Note 4 The output currents given as well as the load regulation can be increased by the addition of external transistors The improvement factor will be roughly equal to the composite current gain of the added transistors Note 5 With zero output the dc line regulation is determined from the ripple rejection Hence with output voltages between 0V and b 5V a dc output variation determined from the ripple rejection must be added to find the worst-case line regulation Note 6 Refer to RETS104X drawing for military specifications for the LM104 2 Typical Performance Characteristics Load Regulation Load Regulation Current Limiting Supply
