HA17431G Series
Adjustable Precision Shunt Regulators
REJ03D0805-0100 Rev.1.00 Mar 10, 2006
Description
The HA17431G series is temperature-compensated adjustable precision shunt regulators. The products have improved features such as wide operating cathode voltage range and precision than the previous products. Output voltage can be set to any value in the range from the reference voltage (Vref) to 40 V by two external resistors. There are two types of reference voltage accuracy sources such as 1.0% standard version and 0.5% A version with higher precision. As for the packages, small surface-mounted types such as MPAK, MPAK-5, and UPAK are available. Therefore, the HA17431G series is suitable for various applications that require high precision and miniaturization.
Features
* High-precision reference voltage : 2.500 V 1.0% (Ta = 25C, Standard version) : 2.500 V 0.5% (Ta = 25C, A version) * Maximum cathode voltage : 40 V * Continuous cathode current : 100 mA * K-REF pin reversing type : HA17432G (UPAK) * Operating temperature range : -40C to +85C
