The TL431ACDBZR from NXP Semiconductors is an adjustable precision shunt regulator designed for various power management applications. It allows for a programmable output voltage ranging from its reference voltage up to 36V, set by two external resistors.
Key electrical characteristics include a typical reference voltage of 2495mV at 25°C with a 1% tolerance (A-Grade). The device supports a sink current capability from 1mA to 100mA and exhibits a typical output impedance of 0.2Ω. It also features a typical temperature drift of 6mV over a 0°C to 70°C range.
This shunt regulator is suitable for applications such as precision current limiting, constant current sinks, and isolated feedback loops in Switch Mode Power Supplies (SMPS). The TL431ACDBZR is supplied in a SOT23 package, designed for surface mounting.
It operates within a temperature range of -40°C to 85°C. The device is AEC-Q100 qualified (grade 1).
The typical reference voltage is 2495 mV (2.495 V) at VKA = Vref, IK = 10 mA, Tamb = 25°C.
The output voltage can be programmed up to 36 V.
The sink current capability ranges from a minimum of 1 mA to a maximum of 100 mA.
The operating ambient temperature range is -40°C to 85°C.
The package is SOT23, surface mount.
The reference voltage tolerance is 1% for the A-grade device.
The typical output impedance is 0.2 Ω.
