Product details
Overview
ADR530BRTZ-REEL7 from Analog Devices is a high-precision 3.0 V shunt voltage reference in SOT-23-3 package, featuring ±0.2% initial accuracy, 40 ppm/°C max temperature coefficient, and 22 μV p-p output noise (0.1 Hz to 10 Hz). It operates from 50 μA to 15 mA and supports trimming over ±0.5% via the TRIM terminal - ideal for battery-powered data acquisition systems requiring stable low-power references.
For engineers reviewing the ADR530BRTZ-REEL7 datasheet, ADR530BRTZ-REEL7 pinout, ADR530BRTZ-REEL7 application, or ADR530BRTZ-REEL7 equivalent, this page delivers verified electrical specs, SC70/SOT-23-3 package mapping, trim-capable shunt topology details, and real-world use cases in portable instrumentation and precision power supplies.
Technical Context
The ADR530BRTZ-REEL7 implements a bandgap-based shunt reference architecture with curvature-compensated ΔVBE summation to achieve low thermal drift. Its three-terminal configuration (V+, V−, TRIM) enables flexible biasing and system-level calibration without external capacitors.
It delivers stable regulation across −40°C to +85°C with dynamic output impedance of 0.2 Ω and turn-on settling time of 2 μs. The TRIM terminal allows post-assembly adjustment of output voltage while preserving temperature coefficient integrity - a key differentiator versus fixed-output alternatives like LM4040.

Pinout & Package
ADR530BRTZ-REEL7 is housed in a 3-lead SOT-23-3 (RT-3) package per JEDEC TO-236-AB, with 0.95 mm pitch and 1.1 mm height. Pin 1 (V+) connects to cathode, Pin 2 (V−) to anode, and Pin 3 (TRIM) to internal trim node - enabling precise system-level voltage adjustment without degrading tempco.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ | Cathode (reference output node) | Provides regulated 3.0 V output; sinks current from external bias resistor and load |
| V− | Anode (ground/reference return) | Return path for reference current; must be connected to system ground or negative rail |
| TRIM | Adjustment terminal | Accepts external potentiometer to shift output ±0.5% without affecting temperature stability |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar shunt voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADR530BKS-REEL7 | Same electrical specs but in SC70 (KS-3) package; 1.25 mm × 0.8 mm vs. SOT-23-3's 2.9 mm × 1.3 mm | Better suited for ultra-dense PCBs where footprint area is constrained | Select ADR530BKS-REEL7 only if board space savings outweigh rework risk from smaller pad geometry |
| LM4040C30IDCKR | ±0.5% initial accuracy, 100 ppm/°C tempco, no TRIM pin, same SOT-23-3 package | Lacks trim capability and has 2.5× higher tempco - requires tighter thermal management | Choose LM4040C30IDCKR only for cost-sensitive, non-critical applications where ±0.5% accuracy suffices |
Compared with ADR530BRTZ-REEL7, ADR530BKS-REEL7 offers identical performance in a smaller footprint but demands finer pitch assembly, while LM4040C30IDCKR trades precision and trim flexibility for lower unit cost - making ADR530BRTZ-REEL7 optimal for calibrated, battery-constrained instrumentation.

FAQ
What is the output voltage tolerance of ADR530BRTZ-REEL7 at 25°C?
The ADR530BRTZ-REEL7 has a Grade B initial accuracy of ±0.2%, corresponding to a guaranteed output voltage range of 2.994 V to 3.006 V at 25°C. This specification is validated per Table 4 in the Rev. E datasheet and applies to all units shipped in the ADR530BRTZ-REEL7 reel format.
Does ADR530BRTZ-REEL7 require an external capacitor for stability?
No, the ADR530BRTZ-REEL7 is internally compensated and remains stable with any capacitive load - including bypass capacitors up to 10 μF. This eliminates the need for external stabilization components, simplifying design and reducing bill-of-materials cost.
How does the TRIM terminal on ADR530BRTZ-REEL7 function in practice?
The TRIM terminal on ADR530BRTZ-REEL7 allows adjustment of the output voltage over a ±0.5% range using an external potentiometer (e.g., AD5273), enabling correction of system-level errors such as PCB trace resistance and amplifier offset without affecting the device's 40 ppm/°C temperature coefficient.
What is the minimum operating current for ADR530BRTZ-REEL7 across temperature?
The ADR530BRTZ-REEL7 maintains regulation with a minimum operating current of 50 μA across its full industrial temperature range (−40°C to +85°C), as specified in Tables 4–6 of the Rev. E datasheet - supporting ultra-low-power operation in battery-backed applications.
Is ADR530BRTZ-REEL7 pin-compatible with LM4040 series references?
Yes, ADR530BRTZ-REEL7 is pin-compatible with LM4040 and LM4050 in the SOT-23-3 package, sharing identical pinout (V+, V−, TRIM/N/C) and mechanical dimensions - allowing drop-in replacement in existing designs without layout changes.
