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

Verify the specific package type against the datasheet, as the S-1132 series includes SOT-23-5, SOT-89-5, and SNT-6A(H) options. Confirm that the environmental code suffix matches your requirements for lead-free or halogen-free specifications. Ensure the ON/OFF logic polarity aligns with your system design before procurement.

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

Select this component when a stable 3.7 V rail is required from a 2.0 V to 6.5 V input source. Consider the package thermal dissipation limits if operating near the maximum 300 mA output current. Verify that the external capacitor ESR remains below 2.0 Ω to prevent oscillation and ensure stability across the specified temperature range.
