Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify that the specific suffix 'Q' confirms automotive grade (AEC-Q100) status and that '-5.0' denotes the fixed 5 V output variant. Ensure the 'NOPB' suffix indicates lead-free and halogen-free compliance. Confirm the 'X' suffix matches the required reel packaging format for your assembly line. Cross-reference the manufacturer part number against official Texas Instruments documentation to ensure authenticity and correct revision level before procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5 V rail is required for automotive applications with input voltages up to 40 V. The 1 A output capability suits moderate load requirements without external pass transistors. The integrated 1.1 MHz frequency allows for smaller inductors compared to lower-frequency alternatives. Consider the SO PowerPAD package for thermal management needs within constrained PCB areas.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2267x family of SIMPLE SWITCHER regulators, which are monolithic integrated circuits combining the controller, driver, and power switch. The LM22672 specifically offers 1 A output current, distinguishing it from the higher-current LM22674/5/6 series and the lower-current LM22671. The Q-series designation indicates automotive qualification, providing enhanced reliability over commercial variants.
