Overview
The ADR3630BRMZ is a precision micropower voltage reference with a nominal output of 3.0 V, housed in an 8-lead MSOP package. It features a maximum temperature coefficient of 3 ppm/°C and an initial output voltage error of ±0.04%. The device supports a sourcing current capacity of up to 70 mA and sinking up to 20 mA, with a low quiescent current of 70 µA. Operating over a –40°C to +125°C range, it accepts input voltages from 3 V to 16 V.
Feature Summary
- High current output capability allows direct replacement for standard LDO regulators
- Proprietary DigiTrim technology ensures high accuracy and low thermal hysteresis
- Integrated enable pin provides low shutdown current for power management
Applications
- Precision power supplies
- Portable instrumentation
- Process transmitters
- Remote sensors
- Medical instrumentation
Procurement Notes
Verify the specific B-grade suffix (BRMZ) matches the required 3 ppm/°C temperature coefficient and ±0.04% initial accuracy specifications. Confirm the 8-lead MSOP package type aligns with PCB layout requirements. Ensure the 3.0 V output voltage meets system design needs before procurement.
Selection Notes
Select this component when high current drive is needed alongside precision referencing. The 3.0 V output suits systems requiring higher headroom than 2.5 V references. Consider the 70 mA sourcing capability if the reference must drive significant loads without external buffering.
Part Context
Part of the ADR3625/ADR3630/ADR3650 family of micropower voltage references. Shares identical performance characteristics regarding noise, drift, and package, differing only in nominal output voltage. Designed for applications requiring stable references with high load-driving capabilities.
Replacement Considerations
ADR3625BRMZ (2.5 V output)
FAQ
What is the minimum load capacitance required for stability?
A minimum load capacitance of 0.1 μF is required for operation.
How does the device handle short circuits?
It includes internal current-limit circuitry that limits source current to approximately 90 mA and sink current to 70 mA during short-circuit conditions.
