Renesas Electronics Corporation Voltage Regulators - Linear HA17431PAJ-E

The HA17431PAJ-E is a temperature-compensated variable shunt regulator designed for applications requiring a variable output voltage. It features a high-precision reference voltage source with an accuracy of ±1% at 2.500 V, making it suitable for precise voltage regulation tasks. The device is available in multiple package options, including the MPAK-5V, which is optimized for high-density circuit boards. This regulator includes a built-in photocoupler bypass resistor, enhancing its functionality in switching mode power supplies. The low temperature coefficient of the reference voltage ensures stable performance across varying temperatures. The HA17431 series is particularly useful in applications where compact size and reliability are critical.
