Detailed Description for TL431ACL5T
Product Overview
TL431ACL5T from STMicroelectronics is a shunt voltage reference IC with an adjustable output. The device provides a minimum/fixed output voltage of 2.495 V and a maximum output voltage of 36 V, with a tolerance of ±1%. It is rated for 100 mA output current and 600 µA cathode current. The operating temperature range is 0°C to 70°C (TA). The component uses a surface-mount SOT-23-5 package, also identified as SC-74A or SOT-753. This configuration supports compact power management and voltage reference functions where a fixed tolerance and defined adjustable reference range are required.
Key Features
- Shunt voltage reference with adjustable output type.
- Minimum/fixed output voltage of 2.495 V and maximum output voltage of 36 V.
- Output current rating of 100 mA.
- Tolerance of ±1%.
- Cathode current of 600 µA.
- Operating temperature range of 0°C to 70°C (TA).
- Surface-mount SOT-23-5 package, also identified as SC-74A and SOT-753.
Applications
- Regulated power supply feedback networks that require an adjustable shunt reference to define a target voltage.
- Analog signal conditioning and measurement circuits that need a reference voltage within the operating range.
- Compact surface-mount control boards where a SOT-23-5 voltage reference can be placed near regulation or sensing circuitry.
Design & Procurement Notes
When selecting TL431ACL5T, confirm that the ambient temperature of the final assembly remains within 0°C to 70°C (TA) and that the circuit can provide the required 600 µA cathode current under the intended operating conditions. The ±1% tolerance and the 2.495 V minimum/fixed output with 36 V maximum output define the adjustable reference range, so the required setpoint and allowable error should be checked against these values. The 100 mA output current rating should be compared with the maximum current demanded by the reference network, including any external resistor or load connection. Because the device uses a surface-mount SOT-23-5 package, verify that the PCB land pattern and assembly process are compatible with the SC-74A or SOT-753 footprint.
