LM809M3X-3.08/NOPB Description

Short technical summary and product information.

The Texas Instruments LM809M3X-3.08/NOPB is a 3-pin voltage supervisor designed for monitoring power supplies in microprocessor and digital systems. It asserts a reset signal when the VCC supply voltage drops below a factory-programmed threshold, ensuring system stability during power-up, power-down, and brown-out conditions.

This supervisor features an active-low, push-pull reset output and is available with multiple threshold options, including 3.08V for this specific part. It offers a typical reset time delay of 240ms and a minimum power-on reset pulse width of 140ms. The device operates over a temperature range of -40°C to 105°C.

Packaged in a SOT-23-3 surface-mount configuration, the LM809M3X-3.08/NOPB is suitable for space-constrained applications. Its low supply current of 15µA typical makes it an efficient choice for power-sensitive designs. This component is a direct upgrade to MAX809 and MAX810 series devices.
