Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the specific ordering suffix SN confirms the U-DFN2020-6 package configuration. Confirm that the -12 designation matches the required 1.2V fixed output voltage for the target design. Ensure compliance with RoHS 3 and REACH standards if environmental regulations apply. Check datasheet revision DS43719 Rev. 1-2 for any updates to absolute maximum ratings or thermal resistance values before finalizing procurement.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when a fixed 1.2V rail is required with up to 600mA load capability. The U-DFN2020-6 package offers a compact footprint suitable for space-constrained PCB layouts. Consider the 60µA quiescent current for battery-powered designs requiring extended standby life. Verify that the input voltage remains within the 2.2V to 6V operating range under all conditions.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators FAQ

What is the minimum output capacitance required for stability?

The device is stable with low ESR ceramic output capacitors of at least 1µF.

How does the enable pin function?

The EN pin is active high; setting it to a logic high level turns on the regulator, while pulling it low disables the output.
