Applications
The ADP667ARZ is used in precision post-regulation stages, reference voltage supplies, and battery-powered industrial instruments where a stable, low-noise output from 1.3 V to 16 V is required at up to 250 mA load. Its wide input range of up to 18 V makes it suitable for automotive accessory circuits and bench-top instrumentation requiring clean DC from unregulated or switching supplies. It is also found in sensor conditioning boards and programmable logic supply rails where tightly regulated voltage and low dropout are critical.

Frequently Asked Questions
What is the minimum dropout voltage of ADP667ARZ and how does it benefit battery-powered designs?
The ADP667ARZ has a maximum dropout voltage of 0.35 V, meaning it can regulate the output even when the input is only 0.35 V above the set output. This low dropout extends battery life in portable instruments by maintaining regulation closer to cell discharge cutoff.
Can ADP667ARZ supply a 3.3 V rail from a 12 V industrial bus while staying within its input rating?
Yes. The ADP667ARZ supports input voltages up to 18 V absolute maximum, so a 12 V industrial supply is well within its operating range. It can regulate a fixed or adjustable output down to 1.3 V at 250 mA, making a 3.3 V rail easily achievable from a 12 V bus.
How does the ±4% output accuracy of ADP667ARZ compare to tighter-spec LDOs for precision reference applications?
At ±4% output accuracy, ADP667ARZ is suited for power supply rails rather than precision voltage references which typically specify ±0.1% or better. For reference-grade accuracy, a dedicated bandgap reference IC should be used, while ADP667ARZ handles post-regulation for logic, analog front-end, and sensor supply rails.
Is ADP667ARZ RoHS-compliant and are there lead-free assembly options?
The standard ADP667ARZ carries a Pbfree Code of No and JESD-609 code e3, indicating it is not in a lead-free finish. Engineers specifying lead-free or RoHS-compliant assemblies should verify with Analog Devices or authorized distributors whether a lead-free variant is available for their production requirements.
