Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify that the suffix 'Q1' confirms AEC-Q100 automotive qualification and 'X' indicates the extended temperature grade. Ensure the package designation matches the required SOT-23-6 form factor for PCB layout compatibility. Confirm RoHS compliance status through official manufacturer documentation prior to integration into production designs.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a wide input voltage range up to 65V is required alongside moderate current demands. It is suitable for designs prioritizing compactness due to the SOT-23-6 package. Consider alternative models if higher output currents or programmable switching frequencies are necessary for specific noise filtering requirements.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LMR516xx-Q1 family of high-voltage synchronous buck converters. It shares architectural similarities with the LMR51610 but offers a lower 600mA output capability. The family is characterized by its ability to operate directly from high-voltage sources common in automotive and industrial sectors without external level shifting.
