TL432BCDBZR

The Texas Instruments TL432BCDBZR is a three-terminal adjustable precision shunt regulator designed for stable thermal performance over various temperature ranges. It allows for an adjustable output voltage from Vref (approximately 2.5V) up to 36V, set using two external resistors. This device boasts an initial accuracy of up to 0.5% at 25°C and operates efficiently with a minimum regulation current of 400µA. Its sink current capability ranges from 1mA to 100mA, with a typical output impedance of 0.2Ω. The TL432BCDBZR is specified for operation across a wide temperature range of -40°C to 125°C, making it suitable for diverse applications. It is available in SOT-23 and SOT-89 packages, supporting various mounting requirements.

This shunt regulator is characterized by its low output noise and a maximum temperature coefficient of 92ppm/°C. The typical temperature drift is noted as 6mV for C temperature range and 14mV for I and Q temperature ranges. These specifications highlight its suitability for applications requiring precise voltage regulation and stability under varying thermal conditions. The adjustable nature of the output voltage provides design flexibility, enabling engineers to tailor the reference voltage to specific circuit needs.
