LM4120IM5X-3.3/NOPB

Voltage Reference Overview

The LM4120IM5X-3.3/NOPB is a precision micropower low dropout voltage reference manufactured by Texas Instruments. It provides a fixed output voltage of 3.3 V with an initial accuracy of ±0.5%. The device operates within an input voltage range of 2 V to 12 V and supports a maximum shunt current of 5 mA. It features a temperature coefficient of 50 ppm/°C and functions reliably across an extended industrial temperature range from -40°C to +85°C. Packaged in a compact SOT-23-5 surface-mount format, it draws a supply current of approximately 275 µA.

Voltage Reference Feature Summary

Precision micropower series voltage reference design
Low dropout operation for efficient power management
Compact five-pin SOT-23 surface-mount packaging

Voltage Reference Applications

Portable battery-powered instrumentation
Data acquisition systems requiring stable reference voltages
Microcontroller analog-to-digital converter references

Voltage Reference Procurement Notes

Verify the specific suffix 'NOPB' indicates lead-free compliance and RoHS status. Confirm the 'IM5X' designation corresponds to the correct industrial temperature grade and tape-and-reel packaging variant. Ensure the 3.3V output matches the target circuit requirements before procurement.

Voltage Reference Selection Notes

Select this component when a fixed 3.3V reference is required with moderate precision (±0.5%) and low quiescent current. It is suitable for space-constrained designs utilizing SOT-23 packages. Consider higher accuracy variants if tighter tolerance or lower temperature drift is necessary for the application.

Voltage Reference Part Context

This part belongs to the LM4120 family of precision voltage references from Texas Instruments. The family offers various fixed output voltages and accuracy grades. The 'IM5X' variant specifically denotes the industrial temperature range and SOT-23-5 package configuration, distinguishing it from automotive or commercial grade alternatives.
