LM431SCCM3X 詳細描述
Product Overview
The LM431SCCM3X from onsemi is a surface-mount shunt voltage reference IC in a SOT-23-3 package. It provides an adjustable output reference with a 2.495V minimum/fixed output voltage and a 36V maximum voltage. The device supports 100 mA output current, ±0.5% tolerance, 50ppm/°C typical temperature coefficient, and 1 mA cathode current. The operating temperature range is -25°C to 85°C (TA).
Key Features
- Shunt reference architecture with adjustable output.
- 2.495V minimum/fixed output and 36V maximum voltage.
- 100 mA output current.
- ±0.5% tolerance and 50ppm/°C typical temperature coefficient.
- 1 mA cathode current.
- Surface-mount SOT-23-3 package (TO-236-3, SC-59).
- Operating temperature range of -25°C to 85°C (TA).
Applications
- Adjustable shunt regulation in surface-mount power supply boards.
- Reference generation for analog measurement and sensor conditioning circuits using a 2.495V reference level.
- Biasing or setpoint generation in control circuits with 1 mA cathode current.
- Voltage monitoring or threshold setting in circuits operating from -25°C to 85°C (TA).
Design & Procurement Notes
When selecting the LM431SCCM3X, verify that the circuit can operate with a shunt reference topology and that the 36V maximum voltage, 100 mA output current, and 1 mA cathode current fit the regulator or monitoring network. The adjustable output and 2.495V minimum/fixed value should be checked against the required reference level, while the ±0.5% tolerance and 50ppm/°C typical temperature coefficient determine the expected accuracy envelope. The SOT-23-3 surface-mount package and -25°C to 85°C (TA) operating range should be matched to board space and ambient conditions.
