Procurement Notes
Verify the specific suffix configuration for the E-Line TO-92 package when sourcing replacements. Confirm that the replacement component matches the required 1% tolerance and 5.0V output specifications. Ensure the substitute part supports the necessary automotive temperature range and operating current limits defined in the original datasheet.
Selection Notes
Select this component for applications requiring space-saving through-hole solutions with high precision. The low minimum operating current makes it suitable for battery-powered designs. Verify that the load capacitance requirements are met, as the device remains stable with capacitive loads without additional compensation components.
