HA17L431UP

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 Mounting area reduced by approx 50% NC NC REF A UPAK K MPAK-5 K 2.9 mm REF 2.5 mm 1.6 mm 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 + − K A REF R2 GND R1 HA17L431 Product Lineup Product Name HA17L431LP HA17L431P HA17L431UP HA17L432UP Package MPAK-5 TO-92 UPAK Application Industrial use 2 HA17L431 Series Pin Arrangement HA17L431P Marking side 1 2 3 HA17L431LP A REF HA17L431UP H...
