Overview

Description

REF3033AIDBZT is a fixed 3.3 V voltage reference from TI (REF3033 family). It provides a stable 3.3 V reference for ADCs/DACs, instrumentation, and precision regulators. The device runs from a single supply and offers low noise, low drift, and good line/load regulation with fast startup.
Note: AIDBZT denotes TI’s specific package variant and tape‑and‑reel packaging for automation.
Common applications:
- Reference for ADCs/DACs and precision measurement systems
- Voltage reference for instrumentation amplifiers and programmable regulators
Package/pinout:
- Refer to the datasheet for the exact pin configuration of the AIDB package; typical variants have V+, VOUT, and GND (with possible enable/trim pins on other variants).
Usage tips:
- Place a decoupling capacitor (e.g., 0.1–1 µF) close to VOUT
- Use within the recommended supply range
- Consider temperature drift for high-precision tasks
For exact specs (initial accuracy, tempco, noise, quiescent current, and packaging details), consult the TI datasheet for REF3033AIDBZT.

Features

- Fixed 3.3 V output reference
- Low-noise, high-precision with low drift (ppm/°C)
- Low quiescent current
- Good line and load regulation
- Short-circuit/overload protection and thermal protection
- Stable performance with proper decoupling capacitor
- 5-pin SOT-23 package (AIDB) with tape & reel option (T)
- RoHS-compliant; available in automotive/industrial temperature ranges depending on grade
Note: Exact electrical specs (accuracy, drift, current) vary by grade and model; please check the datasheet for precise numbers.

Package

SOT-23-5 package (5-pin SOT-23, SC-70-5 variant), RoHS lead-free.

Pinout

Pin count: 3 (SOT-23-3 package).
Function: Fixed 3.3 V voltage reference.
Pinout (typical TI SOT-23-3):
- Pin 1 = VOUT
- Pin 2 = GND
- Pin 3 = VIN
Note: AIDBZT indicates the SOT-23-3 package variant.

Manufacturer

Texas Instruments (TI). TI is a global semiconductor company that designs and manufactures analog, mixed-signal, and embedded processing integrated circuits for diverse electronic applications.

Application

Application areas: - Precision voltage reference for ADCs/DACs in data acquisition, instrumentation, and test equipment; - Sensor conditioning and instrumentation amplifiers; - Calibration and offset references in analog circuits; - Stable supply rail for microcontrollers, regulators, and PLLs; - Battery-powered/portable devices requiring a low-noise 3.3V reference.

Equivalent

Direct pin-for-pin equivalents for REF3033AIDBZT do not exist across vendors. For substitutes, look for other 3.3 V fixed voltage references with similar tolerance, tempco and current. Common alternatives from major vendors include: Microchip MCP1525-3.3, Linear Technology LT6655-3.3, Maxim MAX603-3.3, and TI REF33xx family. Use an official cross-reference tool to verify exact part numbers and packaging compatibility.
