LM431SBIMFX 詳細描述
Product Overview
The onsemi LM431SBIMFX is a shunt voltage reference IC for power-management and reference-biasing functions. It provides an adjustable output with a 2.495 V output value and a 36 V maximum output, a ±1% tolerance, and a typical temperature coefficient of 50 ppm/°C. The device supports 100 mA output current and has 1 mA cathode current. It uses a surface-mount SOT-23F-3 package with flat leads and operates from -40°C to 85°C ambient.
Key Features
- Shunt reference topology with adjustable output
- 2.495 V output value and 36 V maximum output
- ±1% tolerance and 50 ppm/°C typical temperature coefficient
- 100 mA output current and 1 mA cathode current
- Surface-mount SOT-23F-3 package with flat leads
- -40°C to 85°C operating temperature range
Applications
- Reference biasing for analog front-end and sensor conditioning circuits
- Adjustable set-point reference for power-supply control loops
- Voltage threshold reference in general-purpose electronic systems
Design & Procurement Notes
When designing with this reference, consider the 36 V maximum output, 100 mA output current, and 1 mA cathode current to match the biasing network and load conditions. The ±1% tolerance and 50 ppm/°C typical temperature coefficient should be evaluated against system accuracy requirements across the -40°C to 85°C ambient range. The surface-mount SOT-23F-3 package with flat leads should be matched to the board assembly process, while the shunt adjustable output topology should align with the reference circuit architecture and voltage-setting approach.
