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

Verify the specific suffix 'VAO' confirms AEC-Q100 automotive qualification status. Ensure the ordering code matches the required 5-lead SOT-23 package configuration. Confirm that the fixed 3.3V output specification aligns with the target circuit design requirements before finalizing procurement.

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

Select this component when high input voltage tolerance up to 36V is required alongside low quiescent current. The fixed 3.3V output eliminates external resistor networks needed for adjustable versions. Verify that the 100mA continuous current rating meets the maximum load demand of the application.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This part belongs to the MIC5233 family of high-input voltage, low-IQ LDO regulators. The 'M5' designation indicates the 5-lead SOT-23 package type. The 'VAO' suffix specifically denotes AEC-Q100 automotive qualification and PPAP capability, distinguishing it from standard commercial grade variants within the same series.
