Overview
The ADR3650BRMZ is a precision, micropower voltage reference with a nominal output of 5.0 V and an 8-lead MSOP package. It features a maximum temperature coefficient of 3 ppm/°C (B grade) and ±0.04% initial accuracy. The device provides high current capacity, sourcing up to 70 mA and sinking 20 mA, while maintaining low quiescent current of 70 µA and shutdown current of 1.5 µA. It operates over a -40°C to +125°C range with a maximum input voltage of 16 V and a dropout voltage of 0.15 V at 10 mA.
Feature Summary
- High current output capability allows direct replacement for standard LDO regulators in power supply designs.
- Proprietary DigiTrim technology ensures precise trimming of output voltage and temperature coefficient during production.
- Low thermal hysteresis and long-term drift characteristics enhance system lifetime accuracy.
Applications
- Precision power supplies
- Portable instrumentation
- Process transmitters
- Remote sensors
- Medical instrumentation
Procurement Notes
Verify the specific B-grade designation and 5.0 V output variant when ordering. Confirm that the 8-lead MSOP package matches the target PCB footprint. Ensure the application circuit includes the required minimum load capacitance for stability. Check for any recent product change notifications regarding manufacturing updates.
Selection Notes
Select this component for applications requiring high drive current alongside precision voltage referencing. The low dropout voltage supports operation from inputs close to the output level. Consider the thermal resistance and power dissipation limits if operating near maximum current or elevated temperatures.
Part Context
This part belongs to the ADR36xx family of micropower voltage references from Analog Devices. It shares architectural similarities with the ADR3625 and ADR3630 but offers a fixed 5.0 V output. The family utilizes curvature correction technology for improved temperature stability across the industrial range.

FAQ
What is the minimum load capacitance required for stable operation?
A minimum load capacitance of 0.1 μF is required for operation.
How does the device handle short-circuit conditions?
The device includes internal current-limit circuitry that limits the source current to approximately 90 mA and sink current to 70 mA during a short circuit.
