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

Verify the specific package type matches the design requirements, as the S-1132 series is available in SOT-23-5, SOT-89-5, and SNT-6A(H). Confirm environmental codes (U or G) if lead-free or halogen-free specifications are mandatory. Ensure input and output capacitor selections adhere to the recommended ESR limits to prevent oscillation. Check for any recent product change notifications that might affect pinout or electrical characteristics before finalizing procurement.

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

Select this component when a stable 3.5 V rail is required with minimal quiescent current draw. The positive logic ON/OFF pin configuration suits systems where a high signal enables regulation. Consider thermal dissipation constraints if operating near the maximum 300 mA output current, as power dissipation varies by package. Verify that the input voltage remains sufficiently above the output voltage to maintain regulation under all load conditions.
