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

Verify the specific ordering suffix '7B' corresponds to the required tape and reel packaging quantity and orientation. Confirm that the 'D' designation indicates the inclusion of the auto-discharge feature, as this affects shutdown behavior compared to non-discharge variants. Ensure compatibility with the X2-DFN1010-4 footprint during PCB layout review.

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

Select this variant when a stable 1.5V rail is required with minimal board space due to the compact X2-DFN1010-4 package. The integrated discharge feature makes it suitable for applications requiring rapid power-down states. Verify that the input voltage remains above the minimum threshold of 1.7V to ensure proper regulation under all load conditions.
