The MCP103T-300E/LB is a micropower voltage supervisor designed to ensure reliable operation of microcontrollers by keeping them in reset until the supply voltage stabilizes. It features an ultra-low supply current of 1.75 ¬µA in steady-state, making it suitable for battery-powered applications. The device offers precision monitoring options with various reset thresholds, including 2.93V and 3.08V. The reset output is active-low and utilizes a push-pull configuration, providing a reset delay timer of approximately 120 ms. It is available in compact SOT-23 and SC70 packages, with an extended temperature range of -40¬8C to +125¬8C. The MCP103T-300E/LB is ideal for critical power-monitoring applications in computers, intelligent instruments, and portable devices.
