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

Verify the specific suffix 'E' corresponds to the SOT223 package and '-13' indicates 13-inch tape and reel packaging. Confirm RoHS compliance and green molding compound status against the latest manufacturer datasheet revision DS37274 Rev. 5 - 2. Ensure EN pin handling matches design requirements as it is not available in all package variants.

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

Select this component when a precise 1.2V rail is required with minimal voltage drop across the regulator. The SOT223 package offers higher power dissipation capabilities compared to smaller footprints. Verify that the application load does not exceed 1A and that input voltage remains within the 2.2V to 6.0V operational window for optimal line regulation.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators FAQ

Is the enable pin functional in the SOT223 package?

Yes, the AP7361C-12E-13 in the SOT223 package includes an enable pin. However, the datasheet notes that ON/OFF input operation is not available in SOT223 and TO252 packages for some versions; verify pinout diagrams carefully.

What is the maximum junction temperature before thermal shutdown triggers?

Thermal shutdown protection activates when the junction temperature reaches approximately +150°C, disabling the output until the temperature cools to around +130°C.
