LOG114AIRGVR – TEXAS INSTRUMENTS

The LOG114AIRGVR is a surface-mount, 6-pin SOT-23 packaged, low-power, high-accuracy voltage regulator specifically designed for precision analog applications requiring stable 1.8V output. It utilizes a low-noise, low-dropout (LDO) topology, achieving a quiescent current of only 15µA, making it ideal for battery-powered devices. The device operates within an input voltage range of 2.5V to 5.5V, maintaining a tight output voltage tolerance of ±1% over temperature and load variations. Its internal over-temperature protection and short-circuit protection ensure robust operation. The LOG114AIRGVR features a fast transient response time of less than 50ns, minimizing output voltage fluctuations under dynamic load conditions. Common use cases include precision analog-to-digital converters (ADCs), low-power microcontrollers, and sensor interfaces where stable, low-noise 1.8V rails are crucial. Its key advantages are its ultra-low quiescent current, high accuracy, and small form factor, allowing designers to optimize power consumption and board space in sensitive applications. The device’s robust protection features enhance system reliability.
