Frequently Asked Questions
What is the output voltage range of the TLV431ACDBZR?
The TLV431ACDBZR provides an adjustable output voltage from 1.24V (its internal reference voltage) up to 6V, set using two external resistors. This makes it suitable for low-voltage regulation applications where standard 2.5V references are too high.
What package does the TLV431ACDBZR use and what are its pin dimensions?
The TLV431ACDBZR is housed in a SOT-23-3 (R-PDSO-G3) surface-mount package with 3 pins. This small footprint is ideal for compact PCB layouts in portable and space-constrained electronic designs.
What are typical applications for the TLV431ACDBZR?
Typical applications include precision voltage references in switching power supplies, linear regulators, battery chargers, voltage monitors, and error amplifiers. Its low 1.24V reference threshold makes it especially useful in 3.3V and 5V systems requiring accurate low-voltage sensing.
Is the TLV431ACDBZR RoHS compliant?
Yes, the TLV431ACDBZR is fully RoHS compliant and lead-free (Pb-free code: Yes, JESD-609 code: e4), making it suitable for use in environmentally regulated products and green manufacturing processes.
