Product Overview: TPS3125L30DBV from Texas Instruments

The TPS3125L30DBV is a compact, low-power supervisory circuit from Texas Instruments, designed to monitor power supplies in digital systems. It ensures that the system voltage remains within acceptable limits, providing a reliable reset signal to the processor when necessary. This product is particularly suitable for battery-powered equipment, where power conservation is crucial.

With a precise 3.0V threshold, the TPS3125L30DBV provides an active-low reset signal. It features a built-in delay that holds the reset signal for a minimum of 200ms after the supply voltage exceeds the threshold, ensuring that the system has stabilized before allowing the processor to run. This delay feature is critical for systems that require a stable boot-up sequence.

Key Features

  • Voltage Threshold: The device has a preset threshold voltage of 3.0V, which is ideal for 3.3V-powered systems.
  • Power-On Reset Delay: A fixed delay time of 200ms provides a reliable reset signal to the processor after power-up.
  • Low Supply Current: The TPS3125L30DBV is optimized for low-power consumption, drawing only 9µA (typical) of supply current, making it suitable for battery-powered applications.
  • Temperature Range: It operates over a wide temperature range of -40°C to +85°C, accommodating various operating environments.
  • Package Type: The device comes in a small 6-pin SOT-23 package, which is ideal for space-constrained applications.


The TPS3125L30DBV is versatile and can be used in a variety of applications, including:

  • Portable/Battery-Powered Devices
  • Microprocessor/Microcontroller Systems
  • Intelligent Instruments
  • Notebooks and PDAs
  • Industrial Controls

This supervisory circuit from Texas Instruments is a critical component for systems that require consistent monitoring and management of power supply levels. Its small size, low power consumption, and precision make the TPS3125L30DBV an excellent choice for designers looking to enhance the reliability of their digital systems.
