HA17L431 Series High-Precision Variable Shunt Regulators ADE-204-029B (Z) 3rd Edition Apr. 1999 Description The HA17L431LP(MPAK-5) / P(TO-92) / UP(UPAK) are temperature-compensated variable shunt regulators. These ICs can operate at about half voltage in comparison with HA17431V series. They can be replaced for simple Zener diode and they can also be used for switching power supply secondary-side error amplification circuit. MPAK-5, TO-92 and UPAK packages are available. The MPAK-5 package, in particular, is suitable for high-density mounting, with a mounting area approximately half that of Hitachi’s UPAK products. 4.5 mm A 2.9 mm REF Mounting area reduced by approx 50% 2.5 mm 1.6 mm NC NC REF A K K UPAK MPAK-5 Features • • • • • • On-chip high-precision reference voltage source: 1.240 V ± 1.5% (Ta = 25°C) Small reference voltage temperature coefficient: 30 ppm/°C Typ Maximum cathode voltage: 16 V Maximum cathode current: 50 mA Minimum cathode current: 200 µA Typ Operating temperature range: –20 to +85°C Application Example • Reference voltage generation circuits, etc. HA17L431 Series Block Diagram K + − REF 1.240 V A Application Circuit Example Switching Power Supply Secondary-Side Error Amplification Circuit Vout R R1 + − K A REF HA17L431 R2 GND Product Lineup Product Name Package Application HA17L431LP MPAK-5 Industrial use HA17L431P TO-92 HA17L431UP UPAK HA17L432UP 2 HA17L431 Series Pin Arrangement HA17L431P Marking side 1 HA17L431LP A 2 3 HA17L431UP HA17L432UP Marking side Marking side REF 5 4 Marking side 1 2 3 REF K NC NC MPAK-5 A K 1 2 3 1 2 3 REF A K K A REF UPAK TO-92 UPAK Absolute Maximum Ratings Rated Value Item Symbol HA17L431LP HA17L431P HA17L431UP HA17L432UP Unit Note Cathode voltage VKA 16 16 16 16 V 1 Continuous cathode current IK –30 to +50 –30 to +50 –30 to +50 –30 to +50 mA Reference input current Iref –0.05 to +5 –0.05 to +5 –0.05 to +5 –0.05 to +5 mA Power dissipation PT 150 500 800 800 mW Operating temperature Topr –20 to +85 –20 to +85 –20 to +85 –20 to +85 °C Storage temperature Tstg –55 to +150 –55 to +150 –55 to +150 –55 to +150 °C 2 Notes: 1.

Note that the product code and marking pattern are different. The patterns are laser-marked.
