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

Verify the specific ordering suffix against the manufacturer's datasheet to confirm environmental codes and packing specifications. Ensure the selected variant matches the required package type and logic level for the ON/OFF pin. Confirm compliance with RoHS and halogen-free requirements if specified for the application environment.

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

Select this component for applications requiring a stable 2.6 V rail with minimal quiescent current. The B-type designation indicates positive logic for the ON/OFF pin, where a High signal activates the regulator. Ensure the input voltage remains at least 1.0 V above the output voltage for optimal performance and verify that the load current does not exceed the package's thermal dissipation limits.
