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

Verify the component status before procurement as this specific part number is designated as Not Recommended for New Design (NRND). Confirm that existing inventory or legacy designs can accommodate the SOT-89 package dimensions and pinout configuration. Ensure compliance with RoHS and Green manufacturing standards required by the specification.

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

Select this component for applications requiring a stable 1.2V rail in space-constrained designs utilizing the SOT-89 footprint. Consider the NRND status when planning long-term production cycles. Evaluate alternative packages like SOT-23-3 if layout flexibility allows for future design iterations.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This part belongs to the AP2138/2139 series of ultra-low quiescent current CMOS LDOs. While the AP2139 variant includes an enable function, the AP2138 series lacks this feature. The manufacturer recommends using the AP7354 for new designs instead of this legacy series.
