LM120QML LM120QML Series 3-Terminal Negative Regulators Literature Number: SNVS368 LM120QML Series 3-Terminal Negative Regulators drain current of the devices allows this technique to be used with good regulation. General Description The LM120 series are three-terminal negative regulators with a fixed output voltage of -5V, -12V, and -15V, and up to 1.5A load current capability. Where other voltages are required, the LM137 and LM137HV series provide an output voltage range of -1.2V to -47V. The LM120 needs only one external component--a compensation 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 assure satisfactory system operation. Exceptional effort has been made to make the LM120 Series immune to overload conditions. The regulators have current limiting which is independent of temperature, combined with thermal overload protection. Internal current limiting protects against momentary faults while thermal shutdown prevents junction temperatures from exceeding safe limits during prolonged overloads. Although primarily intended for fixed output voltage applications, the LM120 Series may be programmed for higher output voltages with a simple resistive divider. The low quiescent Features Preset output voltage error less than 3% Preset current limit Internal thermal shutdown Operates with input-output voltage differential down to 1V Excellent ripple rejection Low temperature drift Easily adjustable to higher output voltage LM120 Series Packages and Power Capability Rated Power Dissipation Design Load Current TO-3 (K) 20W 1.5A TO-39 (H) 2W 0.5A Package Ordering Information NS Part Number SMD Part Number NS Package Number Package Description LM120H-5.0/883 H03A 3LD T0-39 Metal Can LM120H-12/883 H03A 3LD T0-39 Metal Can LM120H-15/883 H03A 3LD T0-39 Metal Can LM120K-12/883 K02C 2LD T0-3 Metal Can LM120K-15/883 K02C 2LD T0-3 Metal Can LM120KG-5 MD8 (Note 1) Bare Die LM120KG-12 MD8 (Note 1) Bare Die LM120KG-15 MD8 (Note 1) Bare Die Note 1: FOR ADDITIONAL DIE INFORMATION, PLEASE VISIT THE HI REL WEB SITE AT: www.national.com/analog/space/level_die Connection Diagrams 20150113 20150114 Bottom View Steel Metal Can Package TO-3 (K) See NS Package Number K02C (c) 2010 National Semiconductor Corporation 201501 Bottom View Metal Can Package TO-39 (H) See NS Package Number H03A www.national.com LM120QML Series 3-Terminal Negative Regulators December 16, 2010 LM120QML Schematic Diagrams -5V 20150118 -12V and -15V 20150119 www.national.com 2 LM120-5 Power Dissipation Input Voltage Input-Output Voltage Differential Junction Temperatures Storage Temperature Range -25V 25V LM120-12 Internally Limited -35V 30V 150C LM120-15 -40V 30V -65C TA +150C -55C TA +125C 300C Operating Temperature Range Lead Temperature (Soldering, 10 sec.)
