LM4040AIM3-5.0 Description

The LM4040AIM3-5.0 from Texas Instruments is a high-precision shunt voltage reference designed for applications requiring stable and accurate voltage regulation. This fixed 5V output reference features an exceptional ±0.1% tolerance and a low temperature coefficient of 100ppm/°C, ensuring reliable performance across varying environmental conditions. Packaged in a compact SOT23-3 form factor and delivered in Tape & Reel (TR), it is optimized for surface-mount assembly. With a 15 mA output current capability and low 80 µA cathode current, it balances power efficiency with precision. The device also exhibits low noise (80µVrms from 10Hz to 10kHz), making it suitable for noise-sensitive circuits.

LM4040AIM3-5.0 Features

• High Accuracy: ±0.1% initial tolerance for precision voltage referencing.
• Low Temperature Drift: 100ppm/°C ensures stability over temperature variations.
• Low Noise: 80µVrms noise performance ideal for analog and mixed-signal systems.
• Low Power Operation: 80 µA cathode current minimizes power consumption.
• Compact Package: SOT23-3 footprint saves board space in dense layouts.
• Wide Compliance: RoHS3 and REACH compliant, with MSL 1 (Unlimited) moisture sensitivity.
• Last Time Buy Status: Available for final procurement before discontinuation.
