LT1431MJ8

Voltage Reference Overview

The LT1431MJ8#PBF is an adjustable shunt voltage regulator in an 8-lead hermetic CERDIP package. It features a guaranteed 0.4% initial reference voltage tolerance and 0.3% typical temperature stability. The device provides 100mA sink capability with a nominal internal current limit. On-chip divider resistors allow configuration as a 5V shunt regulator with 1% initial voltage tolerance without external components. Output voltage is programmable between 2.5V and 36V using two external resistors.

Voltage Reference Feature Summary

• Adjustable shunt voltage regulator with high precision
• On-chip resistive divider for standalone 5V operation
• Hermetic 8-lead CERDIP packaging

Voltage Reference Applications

• Linear regulators
• Adjustable power supplies
• Switching power supplies

Voltage Reference Procurement Notes

Verify the specific ordering suffix to confirm the J8 ceramic DIP package and lead-free finish designation. Confirm that the component meets military-grade environmental requirements associated with hermetic sealing. Ensure compatibility with high-temperature operating ranges up to 125°C during integration.

Voltage Reference Selection Notes

Select this variant when hermetic sealing is required for harsh environments. The MJ8 suffix indicates the military-grade temperature range of -55°C to 125°C. Use this part instead of plastic packages if moisture resistance or long-term reliability under extreme thermal cycling is critical for the application design.

Voltage Reference Part Context

This component belongs to the LT1431 family of programmable references manufactured by Analog Devices Inc. The family includes various package options such as plastic SOIC, PDIP, and TO-92. The MJ8 specifically denotes the hermetic ceramic dual in-line package suitable for demanding industrial or aerospace applications requiring robust physical protection.
