1 / 12 page TLH7767 November 1994 LM120LM320 Series 3-Terminal Negative Regulators General Description The LM120 series are three-terminal negative regulators with a fixed output voltage of b5V b12V and b15V and up to 15A load current capability Where other voltages are required the LM137 and LM137HV series provide an output voltage range of b12V to b47V The LM120 need only one external componenta compen- sation capacitor at the output making them easy to apply Worst case guarantees on output voltage deviation due to any combination of line load or temperature variation as- sure satisfactory system operation Exceptional effort has been made to make the LM120 Se- ries immune to overload conditions The regulators have current limiting which is independent of temperature com- bined with thermal overload protection Internal current limit- ing protects against momentary faults while thermal shut- down prevents junction temperatures from exceeding safe limits during prolonged overloads Although primarily intended for fixed output voltage applica- tions the LM120 Series may be programmed for higher out- put voltages with a simple resistive divider The low quies- cent drain current of the devices allows this technique to be used with good regulation Features Y Preset output voltage error less than g3% Y Preset current limit Y Internal thermal shutdown Y Operates with input-output voltage differential down to 1V Y Excellent ripple rejection Y Low temperature drift Y Easily adjustable to higher output voltage LM120 Series Packages and Power Capability Rated Design Device Package Power Load Dissipation Current LM120LM320 TO-3 (K) 20W 15A TO-39 (H) 2W 05A LM320 TO-220 (T) 15W 15A LM320M TO-202 (P) 75W 05A Typical Applications Dual Trimmed Supply TLH7767 – 3 Fixed Regulator TLH7767 – 2 Required if regulator is separated from filter capacitor by more than 3 For value given capacitor must be solid tantalum 25 mF aluminum electrolytic may be substituted Required for stability For value given capacitor must be solid tantalum 25 m F aluminum electrolytic may substituted Values given may be increased without limit For output capacitance in excess of 100 mF a high current diode from input to output (1N4001 etc) will protect the regulator from momentary input shorts C1995 National Semiconductor Corporation RRD-B30M115Printed in U S A |
