Voltage Regulators - DC DC Switching Regulators datasheet and documents for LM25007SD

LM25007SD

Voltage Regulators - DC DC Switching Regulators Overview

The LM25007SD is a synchronous step-down switching regulator from Texas Instruments, designed for wide input voltage applications. It operates with an input voltage range of 9V to 42V and delivers a maximum output current of 500mA. The device utilizes a constant on-time control architecture with a fixed switching frequency of 800kHz. It features an adjustable output voltage starting from a minimum of 2.5V. The component is housed in an 8-pin WSON-EP package and supports operation across an extended temperature range from -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Constant on-time control architecture for fast transient response
Integrated synchronous rectification for high efficiency
Wide input voltage capability suitable for industrial supplies

Voltage Regulators - DC DC Switching Regulators Applications

Industrial point-of-load regulation

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix (e.g., SDX/NOPB) against the datasheet to confirm pinout and thermal pad configuration. Ensure the ordering code matches the required tape-and-reel or cut-tape packaging format. Confirm RoHS compliance status through official manufacturer documentation before finalizing procurement specifications.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a compact solution is required for 42V input systems. The 800kHz frequency allows for smaller external passive components compared to lower-frequency regulators. Verify that the load current does not exceed the 500mA limit and that the input voltage remains within the specified 9V to 42V window for optimal performance.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM25007 family of simple switcher regulators. It shares architectural similarities with other TI buck converters but is distinct due to its specific constant on-time control loop and 42V input rating. It serves as a drop-in replacement for legacy non-synchronous regulators in space-constrained designs requiring moderate current capabilities.
