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

Verify that the specific part number matches the required package type SOT-25 and the designated D series variant which includes the pull-down resistor on the CE pin. Confirm compliance requirements such as EU RoHS and halogen-free status are met for the intended manufacturing environment. Ensure the ordering suffix corresponds to the correct reel quantity specifications provided by the manufacturer.

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

Select this component when board space optimization is critical due to the elimination of external load capacitors. Choose the D series specifically if a default OFF state is required when the control pin is left open. Consider the 2.1V fixed output level against the available 0.05V increment range to ensure compatibility with downstream circuitry requirements.
