HA17L431/HA17L431A Series High-Precision Variable Shunt Regulators ADE-204-029D (Z) Rev.4 Dec. 2000 Description The HA17L431LP(MPAK-5) / P(TO-92) / UP(UPAK) and the HA17L431ALP(MPAK-5) / AP(TO-92) 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 ± 1.0% (Ta = 25°C) [HA17L431A] : 1.240 V ± 1.5% (Ta = 25°C) [HA17L431] • 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/HA17L431A 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/HA17L431A R2 GND Product Lineup Reference Voltage Normal Version ±1.5% 1.222 to 1.258 V 1.240V Item Industrial use HA17L431LP Ο Ο MPAK-5 −20 to +85°C TO-92 Ο HA17L431AP 2 Package Operating Temperature Range Ο HA17L431ALP HA17L431P A Version ±1.0% 1.227 to 1.253 V 1.240V HA17L431UP Ο HA17L432UP Ο UPAK HA17L431/HA17L431A Series Pin Arrangement HA17L431P/ HA17L431AP Marking side HA17L431LP/ HA17L431ALP A 1 2 3 HA17L431UP HA17L432UP Marking side Marking side REF 5 4 Marking side 1 2 3 NC NC MPAK-5 K REF A TO-92 K 1 2 3 1 2 3 REF A K K A REF UPAK UPAK 3 HA17L431/HA17L431A Series Absolute Maximum Ratings (Ta = 25°C) Rated Value Item Symbol HA17L431LP/ HA17L431ALP HA17L431P/ HA17L431AP HA17L431UP/ HA17L432UP Unit Note Cathode voltage VKA 16 16 16 V 1 Continuous cathode current IK −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 mA Power dissipation PT 150 500 800 mW Operating temperature Topr −20 to +85 −20 to +85 −20 to +85 °C Storage temperature Tstg −55 to +150 −55 to +150 −55 to +150 °C 2 0.6 0.5 0.5W −4mW/°C (1) 0.4 0.3 0.26 0.2 0.1 0.15W −1.2mW/°C (2) 0.078 −20 0 25 50 75 85 150 Ambient temperature Ta (°C) (1): HA17L431P/AP (2): HA17L431LP/ALP 4 Power dissipation PT (W) Power dissipation PT (W) Notes: 1.
