概述

Description

The LM4040D20IDBZR is a fixed 2.0 V shunt voltage reference from the LM4040 family. It behaves as a precision regulator that clamps its cathode-to-anode voltage at ~2.0 V as long as a bias current is supplied.
Key points
- Package: 3-pin, RoHS-compliant (IDBZR variant) in a small SOT-23 style package.
- Operation: Requires a resistor from a supply to the reference’s cathode to set current; anode goes to ground. It regulates over a wide load range.
- Current range: Imin about tens of microamps to maintain regulation; Imax typically up to ~20 mA.
- Performance: Low dynamic impedance and low noise; typical initial accuracy around ±0.5% at 25°C; temperature coefficient on the order of tens of ppm/°C (varies by lot).
- Applications: ADC/DAC references, precision biasing, low-power sensor circuits, portable devices.
Notes
- Exact pinout depends on package variant; consult the datasheet for the LM4040D20IDBZR pin configuration and recommended operating conditions.

Features

Here are the key features of the LM4040D20IDBZR (2.0 V fixed shunt reference):
- Fixed 2.0 V shunt voltage reference (LM4040D20)
- Two-terminal device (anode and cathode); no external resistor network required
- Small, RoHS-compliant package (SOT-23 style; IDBZR code)
- Low dynamic impedance with good line and load regulation
- Low noise and good temperature stability
- Wide operating current range (bias from microamps to tens of milliamps)
- Very high accuracy at room and temperature extremes
- Suitable for precision references in ADC/DAC, voltage reference circuits, and microcontroller systems

Package

SOT-23 3-pin surface-mount package (Pb-free/ RoHS).

Pinout

Pin count: 3 pins (SOT-23-3 package).
Function: Fixed 2.0 V shunt voltage reference/regulator. It clamps the voltage to ~2.0 V by shunting current to ground (anode to ground, cathode to the node being regulated; the third pin is typically No Connect).

Manufacturer

Manufacturer: Texas Instruments (TI).
What kind of company: TI is an American multinational semiconductor company that designs and manufactures analog and mixed-signal integrated circuits and embedded processing products.

Application

Applications:
- Precision 2.0 V shunt reference for ADC/DAC front-ends
- Reference for comparators, op-amps, and instrumentation amplifiers
- Voltage reference in power-management and regulator circuits
- Battery-powered/portable devices needing low-noise, stable references
- Sensor interfaces and data-logging systems
