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

This part number is officially listed as obsolete and no longer manufactured by ABLIC Inc. Buyers must verify availability through authorized distributors or secondary markets. Replacement components should be sourced from the manufacturer's official substitute list to ensure compatibility. Due to its discontinued status, lead times and stock levels are unpredictable. Validate RoHS3 compliance and package integrity upon receipt. Confirm that any alternative parts meet the original electrical specifications before integration into designs.

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

Select this component only if legacy design compatibility is required. The fixed 1.5 V output limits flexibility compared to adjustable regulators. Verify that the 200 mA current rating meets system peak demands. The SOT-23-5 package constrains thermal performance; ensure adequate PCB copper area for heat dissipation given the 300 mW power dissipation limit. Consider modern equivalents if new designs allow, as obsolescence may impact long-term supply chain stability.
