The TS432ACT is a dual precision adjustable shunt regulator manufactured by Taiwan Semiconductor. Similar to the TS431, it functions as a programmable zener diode, but it houses two independent adjustable shunt regulators in a single package. This allows for space-saving designs and the ability to regulate two separate voltages with one IC.

Applications:

• Dual Voltage References: Provides two independent stable voltage references for various circuits.
• Dual Error Amplifiers: Implemented in feedback loops for dual voltage and current regulation.
• Dual Adjustable Power Supplies: Enables the creation of dual adjustable voltage power supplies.
• Over-Voltage Protection Circuits: Provides over-voltage protection in sensitive electronic equipment where multiple voltage rails exist.
• Independent Comparator Circuits: Used in independent comparator circuits for threshold detection.

Features:

• Dual Adjustable Output Voltage: Each regulator's output voltage can be adjusted to any value between Vref (2.5V) and 36V using two external resistors.
• Low Output Noise: Provides a clean and stable output voltage with minimal noise for each channel.
• Low Temperature Coefficient: Maintains stable performance over a wide temperature range.
• Sink Current Capability: Each regulator is capable of sinking current, making it suitable for various applications.
• Wide Operating Current Range: Operates efficiently over a wide range of operating currents for both regulators.
• SO-8 Package: Surface mount package for easy integration into PCBs.

Benefits:

• Dual Precise Voltage Regulation: Provides accurate and stable voltage regulation for two independent circuits.
• Space-Saving Design: Integrates two regulators into a single package, saving board space.
• Flexibility in Voltage Adjustment: Allows for easy adjustment of each output voltage to meet specific application requirements.
• Stable Performance: Maintains stable performance over a wide range of operating conditions.
• Low Noise: Minimizes noise in the output voltage for both channels.
• Cost-Effective Solution: Provides a cost-effective solution for dual voltage regulation and reference applications.

Additional Details:

The TS432ACT is available in an SO-8 package. The output voltage for each regulator is set using two external resistors according to the formula: Vout = Vref * (1 + R1/R2), where Vref is the internal reference voltage (typically 2.5V). Each regulator operates independently. Detailed application notes and design guidelines are available from Taiwan Semiconductor to assist with implementation.
