Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix TL-3022 against the official datasheet to confirm the fixed output configuration of 1.2 V and 1.85 V. Ensure the 20-WFBGA package footprint matches the target PCB layout. Confirm RoHS compliance status and check for any recent Product Change Notifications regarding manufacturing site changes or material updates before finalizing procurement orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a compact solution is required for generating two distinct low-voltage rails from a single 5 V source. The fixed outputs simplify design time by removing external divider resistors. Consider the 600 mA per channel limit to ensure adequate headroom for peak load currents. The 2 MHz frequency allows for smaller passive components compared to lower-frequency alternatives, aiding in overall board size reduction.
