A431A规格书详情
DESCRIPTION
The A431A and A432A devices are three-terminal adjustable shunt regulators, with specified thermal stability over applicable automotive, commercial, and military temperature ranges.
The output voltage can be set to any value between Vref (approximately 2.5V) and 36V, with two external resistors. These devices have a typical output impedance of 0.15 Ω. Active output circuitry provides a very sharp turn-on characteristic, making these devices excellent replacements for Zener diodes in many applications, such as onboard regulation, adjustable power supplies, and switching power supplies.
The A432A device has exactly the same functionality and electrical specifications as the A431A device, but has different pinouts. Both the A431A and A432A devices are offered in two grades, with initial tolerances (at 25°C) of 0.5 for A, and 1, for the B. In addition, low output drift versus temperature ensures good stability over the entire temperature range. The A431A and A432A devices are characterized for operation from–40°C to 125°C.
The A431A and A432A are available in SOT-23 package.
