UNISONIC TECHNOLOGIES CO., LTD TL432D LINEAR INTEGRATED CIRCUIT 0.8V PRECISION ADJUSTABLE SHUNT REFERENCE REGULATORS DESCRIPTION The UTC TL432D is a three-terminal adjustable shunt regulator highly accurate 0.8V band gap reference with 1%, 2% tolerance. The device offers thermal stability, wide operating current (50mA) and an extended temperature range of 0° to 105°C for operation in power supply applications. The UTC TL432D offers a wide operating voltage range of up to 12V and is an excellent choice for voltage reference requirements in an isolated feedback circuit for 3.0V ~ 3.3V switching mode power supplies. The tight tolerance guarantees a lower design cost for the power supply manufacturer by virtually eliminating the need for an extra power supply manufacturing process of the power supply. FEATURES * Temperature-Compensated: 50ppm/°C * Internal Amplifier with 50mA Capability * Nominal Temperature Range Extended to 105°C * Low Frequency Dynamic Output Impedance:<150mΩ * Low Output Noise * Halogen Free ORDERING INFORMATION Ordering Number 1 2 TL432DG-AB3-R R A TL432DG-AE3-R K R TL432DG-AF5-R X X TL432DG-T92-B R A TL432DG-T92-K R A TL432DG-S08-R K A Note: Pin Code: C: Cathode Pin Assignment Package 3 4 5 6 7 8 K SOT-89 A SOT-23 K R A SOT-25 K TO-92 K TO-92 A X X A A R SOP-8 A: Anode R: Reference X: No Connection www.unisonic.com.tw Copyright © 2009 Unisonic Technologies Co., Ltd Packing Tape Reel Tape Reel Tape Reel Tape Box Bulk Tape Reel 1 of 4 QW-R103-040.B TL432D LINEAR INTEGRATED CIRCUIT MARKING INFORMATION PACKAGE MARKING SOT-23 3 SOT-25 2 1 432DG 4 5 UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 2 of 4 QW-R103-040.B TL432D LINEAR INTEGRATED CIRCUIT BLOCK DIAGRAM CATHODE(K) + - REFERENCE(R) + - 0.8V ANODE(A) UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 3 of 4 QW-R103-040.B TL432D LINEAR INTEGRATED CIRCUIT ABSOLUTE MAXIMUM RATINGS PARAMETER SYMBOL RATINGS UNIT Cathode-Anode Reverse Breakdown VKA 15 V Anode-Cathode Forward Current IAK 1 A Operating Cathode Current IKA 50 mA Reference Input Current IREF 1 mA Junction Temperature TJ 125 °C Operating Temperature TOPR -20 ~ +85 °C Storage Temperature TSTG -40 ~ +150 °C Note: Absolute maximum ratings are those values beyond which the device could be permanently damaged.
