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

This component is designated as Not Recommended for New Design (NRND) by the manufacturer. Verify end-of-life status and availability constraints before finalizing procurement plans. Confirm that existing inventory meets project requirements or initiate transition strategies to recommended replacement parts immediately.

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

Select this part only if utilizing legacy designs requiring the specific AP7370 series characteristics. Ensure input voltage remains between 3.2V and 18V. Verify that the required load current does not exceed 300mA. Consider alternative components from the manufacturer's recommended portfolio for new development projects.

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

The AP7370 series represents a line of wide-input voltage ULDO regulators designed for space-saving applications. The SA suffix specifically denotes the SOT-23-3 package variant. This series integrates a voltage reference, error amplifier, and resistor network to maintain precise output regulation under varying load and line conditions.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

Diodes Incorporated recommends transitioning to the AP7375 series for new designs. Specific pin-compatible alternatives include AP7375-33W5-7 (SOT-25 package). Verify electrical specifications and physical footprint compatibility when evaluating these replacements.
