LM431BQ Precision Programmable Reference
●The LM431BQ is a precision programmable shunt voltage reference that can be used in automotive applications. It is a three-terminal adjustable-output device that can keep stable under all capacitive loads. It requires two external resistors to set the output voltage from V-REF to 36V.
●The LM431BQ features low dynamic impedance, low noise, and low temperature coefficient to ensure a stable output voltage over a wide range of operating temperatures and currents. These high performances make it very suitable for multiple applications, such as precision audio components and flyback switching power supplies.
●This device is AEC-Q100 qualified (Automotive Electronics Council (AEC) standard Q100 Grade 1) and it is suitable for automotive applications.
●The LM431BQ is available in a Green SOT-23 package.
■FEATURES:
●AEC-Q100 Qualified for Automotive Applications Device Temperature Grade 1 T-A = -40℃ to +125℃
●Adjustable Output Voltage: V-REF to 36V
●Sink-Current Capability: 1mA to 100mA
●▲Reference Voltage Tolerance at +25℃: 0.5%
●Temperature Drift: 5mV (TYP)
●Output Impedance: 0.1Ω (TYP)
●▲High Stability under Capacitive Load
●Low Output Noise
●Operating Junction Temperature Range: -40℃ to +125℃
●Available in a Green SOT-23 Package
