Frequently Asked Questions
What is the output voltage specification of the PTL432LIAQDBZRQ1?
The PTL432LIAQDBZRQ1 provides a nominal output voltage of 2.495V with a tight tolerance range of 2.47V minimum to 2.52V maximum. This precision makes it suitable as a voltage reference in analog circuits, ADC reference inputs, and power supply feedback networks requiring stable and accurate voltage.
Is the PTL432LIAQDBZRQ1 qualified for automotive use?
Yes, the PTL432LIAQDBZRQ1 carries automotive qualification as indicated by the 'Q1' suffix in its part number, aligning with AEC-Q100 standards for automotive-grade ICs. It was introduced on May 10, 2019 and is designed for use in vehicles operating across demanding temperature and reliability requirements.
What package does the PTL432LIAQDBZRQ1 use?
The PTL432LIAQDBZRQ1 is housed in a 3-pin SOT-23 surface-mount package (JESD-30 code R-PDSO-G3) with plastic/epoxy body material. The SOT-23 footprint is one of the smallest available for active components, making it ideal for compact automotive PCB designs with limited board space.
What does 'optimized reference current' mean for the PTL432LIAQDBZRQ1?
The optimized reference current feature means the PTL432LIAQDBZRQ1 requires less minimum cathode current to maintain regulation compared to standard TL431 devices. This reduces power consumption in low-power shunt regulator topologies and extends the usable operating range in high-impedance circuit configurations.
