Overview
The HTC TL432CSF is a three-terminal programmable precision shunt regulator featuring a 1.24V bandgap reference with 0.5% tolerance. It operates within a cathode voltage range of VREF to 18V and supports a sink current capability from 1mA to 100mA. The device exhibits an equivalent full-range temperature coefficient of 50ppm/°C and low output noise voltage. Packaged in SOT-23-3L, it provides thermal stability suitable for high-performance applications.
Feature Summary
- Provides a highly accurate 1.24V bandgap reference voltage
- Features wide operating current capability up to 100mA
- Temperature compensated for operation over the full rated range
Applications
- Shunt Regulator
- Voltage Monitoring
- Current Source and Sink Circuits
- Analog & Digital Circuits Requiring Precision References
- Low Output Voltage (3.0V to 3.3V) Switching Power Supply Error Amplifier
Procurement Notes
Verify the specific ordering suffix 'SF' corresponds to the SOT-23-3L package configuration as defined in the manufacturer's official documentation. Confirm that the component meets the required 0.5% initial accuracy tolerance for the intended circuit design before finalizing procurement specifications.
Selection Notes
Select this component when a precise 1.24V reference is required in a compact surface-mount form factor. Ensure the application circuit maintains the cathode current between 1mA and 100mA to guarantee stable regulation. Verify that the maximum cathode voltage does not exceed 18V under all operating conditions.
Part Context
The TL432 series serves as a widely adopted adjustable precision shunt regulator across various electronic designs. Manufactured by HTC (Taejin Technology), this specific part integrates a bandgap reference core into a small footprint, offering a cost-effective alternative to discrete resistor networks for voltage referencing tasks.
Replacement Considerations
Compatible substitutes include the TL432ASF (1% tolerance) or other manufacturers' TL432 variants such as those from Texas Instruments or Diodes Incorporated, provided they match the SOT-23-3L package and electrical characteristics.
