Overview
The HTC TL432ASF is a three-terminal programmable precision shunt regulator featuring a low-voltage bandgap reference of 1.24V with 1% tolerance. It operates within a cathode voltage range from VREF to 18V and supports a sink current capability of 0.1mA to 100mA. The device exhibits an equivalent full-range temperature coefficient of 50ppm/°C and maintains operation across a temperature range of -40°C to 125°C. Packaged in SOT-23-3L, it provides low output noise and dynamic impedance typically at 0.2Ω.
Feature Summary
- Provides a highly accurate 1.24V bandgap reference voltage with guaranteed 1% tolerance for precise regulation applications.
- Features wide operating current capability ranging from 0.1mA to 100mA suitable for various load conditions.
- Offers thermal stability with a full-range temperature coefficient of 50ppm/°C over the extended industrial temperature range.
Applications
- Shunt Regulator
- Voltage Monitoring
- Current Source and Sink Circuits
- Low Out Voltage (3.0V to 3.3V) Switching Power Supply Error Amplifier
Procurement Notes
Verify the specific suffix 'SF' confirms the SOT-23-3L package configuration and tape & reel supply format as documented in the ordering information. Ensure the 'A' designation aligns with the required 1% reference voltage tolerance specifications for your circuit design constraints.
Selection Notes
Select this component when a low-cost, high-performance solution requiring a 1.24V reference is needed. It is particularly suitable for isolated feed circuits in low-voltage switching mode power supplies where thermal stability and wide operating current ranges are critical requirements.
Part Context
The TL432 series serves as a three-terminal shunt voltage reference designed to replace Zener diodes in many applications. The TL432ASF variant specifically utilizes the SOT-23-3L package, offering a compact footprint compared to TO-92 or SOT-89 options while maintaining identical electrical performance characteristics within the same product family.
Replacement Considerations
Cross-reference with other manufacturers' 1.24V adjustable precision shunt regulators in SOT-23 packages. Verify pinout compatibility and tolerance grades before substitution to ensure circuit stability.
