Voltage reference IC EB1859911134 2.495V ±1% in TO-92 package

The EB1859911134 is a precision voltage reference IC that provides a stable 2.495V output with ±1% accuracy in a compact TO-92 through-hole package. Designed for use where a fixed, low-drift reference voltage is required, this component supports measurement, calibration, sensor excitation, and analog circuitry. Its small form factor and standard lead spacing make it suitable for prototyping and easy PCB mounting while delivering consistent performance across normal operating conditions.

Advantages

The voltage reference offers high accuracy and low temperature sensitivity within the specified tolerance, ensuring repeatable reference levels for ADCs, DACs and precision analog circuits. The TO-92 package provides a simple, cost-effective through-hole mounting option that is convenient for breadboarding and manual assembly. Stable output under typical load conditions and a defined nominal voltage simplify circuit design and calibration processes.

How to use

Place the device on the PCB following standard TO-92 pin orientation for the selected footprint and observe correct polarity where applicable. Provide the recommended supply voltage and any required bypass or decoupling capacitors according to the system design to minimise noise and transient effects. Use proper thermal management and avoid exceeding the manufacturer's specified temperature and power dissipation limits to maintain the stated accuracy. Verify the reference with a calibrated meter during initial setup and after final assembly if precise calibration is required.

Usage recommendations

For best results, add a local bypass capacitor close to the device pins to reduce high-frequency noise, avoid large load transients on the reference output, and allow a short warm-up time after power-up before performing precision measurements. When using the TO-92 package in confined spaces, ensure adequate airflow or thermal coupling to the PCB to prevent temperature-induced drift.
