Product Overview
The REF2030AIDDCR is a low-drift, low-power dual-output voltage reference from Texas Instruments for single-supply signal conditioning. It delivers stable 3.0V VREF and matched buffered 1.5V VREF/2 bias output, eliminating external op-amps and resistor dividers for differential ADC/DAC inputs. With typical 8 ppm/°C temperature coefficient and ±0.05% max initial accuracy, it maintains stable precision across -40°C to +125°C industrial range. Ultra-low 10mV dropout only requires minimal supply headroom, extending battery runtime. Compact SOT-23-5 package fits space-limited sensor signal circuits, portable DAQ and precision control systems.
Core Advantages
Integrated Dual-Output Precision (VREF and VREF/2)
Natively delivers a 3.0V reference coupled with an isolated, buffered 1.5V bias output, eliminating external circuit components needed for mid-point referencing in differential data converter systems.
Excellent Thermal Stability
Features a low temperature drift specification of 8 ppm/°C (typical) across a wide industrial thermal spectrum, guaranteeing reliable, long-term precision without calibration shift issues.
Highly Compressed Low-Dropout Performance
Exhibits an ultra-low dropout voltage rating of just 10mV at low loads, allowing developers to design tight voltage regulation margins and extract maximum operation duration from battery systems.
Minimized Board Area and BOM Overhead
Consolidates reference generation, voltage division, and decoupling buffer amplifier blocks into a singular miniature SOT-23 structure, directly reducing board footprint overhead and component cost.

Frequently Asked Questions
Q1: Is your current stock of the REF2030AIDDCR 100% original and genuine factory stock?
A: Yes, we guarantee that all REF2030AIDDCR units in our warehouse are 100% brand-new, genuine components sourced directly from Texas Instruments. Every batch features clean lot codes and is stored and shipped in strict compliance with moisture-barrier and antistatic ESD protocols.
Q2: What is the main design benefit of having both a VREF and a VREF/2 output on the same IC?
A: Modern high-resolution data converters running on single-ended power rails require a stable reference voltage for full-scale measurement along with a mid-supply common-mode voltage (VREF/2) to bias differential analog input signals. Conventionally, this requires external resistor networks and voltage-follower operational amplifiers, which introduce drift errors. The REF2030AIDDCR provides both on a single substrate, ensuring thermal matching and reducing the external bill of materials (BOM).
Q3: What is the dropout voltage constraint for this chip when operating close to a 3.0V output target?
A: The REF2030AIDDCR is a low-dropout (LDO) series reference requiring very little operational headroom. Under zero-load conditions, the minimum headroom is essentially negligible, and it tracks at approximately 10mV under standard 5mA loads. This feature allows it to provide a highly stable 3.0V output even if the input battery rail drops down to 3.02V.
Q4: How can our technical division request an official PDF datasheet, step models, or request volume price quotes?
A: Please submit your request through our Quick Inquiry form available on this product profile page. Our customer and technical engineering support desks will process your criteria and respond within 24 hours.
