Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the complete part number including suffixes to ensure correct packaging and temperature grade. Confirm AEC-Q100 qualification status if required for specific automotive safety integrity levels. Check datasheet for thermal performance requirements in the HTSSOP-16 package under maximum load conditions.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 3.3 V output is required with up to 2 A current capability in automotive environments. The 2.1 MHz frequency allows for smaller inductors compared to lower-frequency alternatives. Ensure input voltage stays within the 3.5 V to 36 V range and consider thermal dissipation for high ambient temperatures up to 150°C.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM53602 series of simple switcher regulators. It shares architectural similarities with other members like the LM536023 but offers specific fixed output and current ratings tailored for mid-power automotive loads.
