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

Verify the end-of-life status before integration into new designs. Confirm that the SSOP-8 package dimensions align with existing PCB footprints. Ensure thermal management strategies account for the 380 mW power dissipation limit under worst-case load scenarios. Validate compatibility with available supply chain sources given the discontinued status.

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

Select this component when dual adjustable LDO rails are required in a compact form factor. Consider the 50 mA current limit for load requirements. Evaluate the -40°C to +85°C temperature range against environmental constraints. Compare against single-channel alternatives if only one polarity is needed to optimize board space.
