Overview
The TSM4925DCS is a monolithic integrated circuit functioning as a very low dropout voltage regulator with an output of 5V. It incorporates additional features including a power-on reset circuit and a programmable reset delay time. The device is designed for supplying microcomputer-controlled systems, particularly in automotive applications. Key electrical characteristics include a very low dropout voltage of less than 0.6V, an operating DC supply voltage range from 6V to 28V, and transient supply voltage capability up to 40V. The output current capability reaches up to 500mA, while maintaining extremely low quiescent current consumption.
Feature Summary
- Integrates a reset circuit that senses the output voltage
- Provides thermal shutdown and short circuit protections
- Allows programmable reset pulse delay via an external capacitor
Applications
- Microcomputer controlled systems
- Automotive applications
Procurement Notes
Verify the manufacturer designation carefully, as the model number L4925 is primarily associated with STMicroelectronics. Confirm the specific datasheet provided by Taiwan Semiconductor Corporation for this part number to ensure accurate pinout and electrical specifications match your design requirements before procurement.
Selection Notes
Select this component when a stable 5V supply is required with minimal voltage drop across the regulator. Consider the programmable reset delay feature if system initialization timing requires synchronization with external events. Ensure the input voltage remains within the specified 6V to 28V range for proper operation.
Part Context
This component belongs to the family of low dropout linear regulators designed for robust performance in noisy environments. It combines power regulation with supervisory functions, reducing the component count in embedded designs. The integration of reset generation simplifies the interface between the power supply and the microcontroller unit.
Replacement Considerations
The L4925 from STMicroelectronics is a functionally similar part with identical electrical parameters and pinout compatibility. Verify package dimensions and thermal characteristics to ensure mechanical fit during replacement.
