Applications
The TS432AILT is widely used as a programmable shunt reference in switch-mode power supplies, where its 1.24 V reference threshold sets output voltages from 1.24 V to 10 V with high precision. It is also deployed in battery charger feedback loops, op-amp bias circuits, and industrial instrumentation that require a stable two-terminal reference in minimal board area. The SOT-23 package makes it especially suitable for portable consumer electronics and space-constrained industrial designs.

Frequently Asked Questions
What is the reference voltage range of TS432AILT and how accurately is the threshold set?
TS432AILT provides an adjustable output range from 1.24 V to 10 V, with the internal reference threshold tightly controlled between 1.234 V and 1.246 V at 25°C. This 12 mV window represents less than 1% initial accuracy, making it suitable for precision feedback regulators and reference networks in power conversion designs.
How does TS432AILT fit into a switch-mode power supply feedback loop compared to a fixed 2.5 V reference?
Unlike a fixed 2.5 V reference, TS432AILT allows output voltages as low as 1.24 V to be programmed with just 2 external resistors, supporting modern low-voltage rails in CPU power stages and DDR memory supplies. Its two-terminal shunt topology integrates directly into an optocoupler feedback path, reducing component count while achieving accuracy within 12 mV of the 1.24 V internal threshold across the SOT-23 footprint.
For a portable 3.3 V Li-ion charger design, does the SOT-23 package of TS432AILT save meaningful board area versus a TO-92 alternative?
Yes. The SOT-23 3-pin package of TS432AILT occupies roughly 3 mm x 1.75 mm, compared to about 5 mm x 3.5 mm for a TO-92, saving more than 60% PCB footprint area. In a 3.3 V Li-ion charger or 5 V USB adapter, this footprint reduction allows tighter component placement and supports high-density designs targeting less than 1 cm² total reference circuitry.
What factory lead time should procurement teams plan for TS432AILT in volume orders?
TS432AILT carries a factory lead time of 12 weeks from STMicroelectronics, which is typical for standard analog references in SOT-23. Procurement teams working on programs requiring more than 1000 units should place orders at least 3 months ahead to avoid supply gaps, and consider holding 4 to 6 weeks of safety stock at the distributor level for production continuity.
