TEXAS INSTRUMENTS Voltage Reference, Precision Micropower, Shunt - Fixed, TO-92 - 5V

The TEXAS INSTRUMENTS Voltage Reference is a high-precision, micropower shunt regulator from the acclaimed LM4040 product range. Engineered to deliver an exceptionally stable and accurate fixed reference voltage, this component is an indispensable building block for a wide array of electronic circuits where reliable voltage regulation and measurement are critical. Its precision performance ensures consistent operation of sensitive analogue components, making it ideal for applications demanding low noise and high stability over varying conditions.

This device features a stringent 0.1% initial accuracy and a low temperature coefficient of 100ppm/°C, guaranteeing minimal deviation from the target voltage across a broad operating temperature range from -40°C to 85°C. The shunt configuration allows for simple integration into circuits, providing a stable voltage reference point independent of power supply fluctuations. Housed in a compact and industry-standard TO-92 (TO-226AA-3) through-hole package with 3 pins, it offers robust mechanical construction and ease of manual or automated assembly onto printed circuit boards (PCBs).

Key Applications

Precision voltage references are fundamental in modern electronics. This TEXAS INSTRUMENTS component is perfectly suited for use in precision analogue-to-digital converters (ADCs), digital-to-analogue converters (DACs), and voltage regulators where a stable reference is paramount for accurate signal conversion. It is also highly effective in portable battery-powered equipment, medical instrumentation, test and measurement gear, and data acquisition systems, where its micropower consumption helps maximise operational life. Furthermore, it serves as an excellent bias reference for zener diodes and in power supply supervision circuits.

With its proven reliability and compliance with industry standards, this voltage reference is
