Frequently Asked Questions
What type of device is the PATL432LIAIDBZR and how is the output voltage set?
The PATL432LIAIDBZR is a three-terminal programmable precision shunt voltage reference. The output reference voltage is set by connecting two external resistors in a voltage divider configuration between the cathode, reference input, and ground. This allows the output to be programmed to any voltage above the minimum reference voltage of the device.
What is the package type and pin count for the PATL432LIAIDBZR?
The PATL432LIAIDBZR is housed in a SOT-23 3-pin package, one of the smallest standard transistor outline surface-mount packages available. Its three terminals are cathode (K), anode (A), and reference input (R), providing a compact footprint suitable for high-density PCB designs in portable and space-constrained applications.
What makes the PATL432LIAIDBZR suitable for battery-powered applications?
The PATL432LIAIDBZR is designed with a low quiescent current (Iq) characteristic that minimizes standby power consumption. Combined with its small SOT-23 package, this makes it ideal for battery-operated devices including IoT sensors, portable medical devices, and wearable electronics where every microamp of quiescent current impacts battery life.
How does the PATL432LIAIDBZR compare to the TL432 shunt regulator?
The PATL432LIAIDBZR is an enhanced version of the standard TL432 shunt regulator, offering higher bandwidth and lower quiescent current optimized for modern precision applications. The PAT prefix variants from Texas Instruments typically include improved accuracy specifications and better temperature performance compared to the classic TL431/TL432 family.
