Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes
Verify the specific suffix 'WR' corresponds to the SOT-25 package variant when ordering. Confirm that the 1.8V output version meets the target application requirements. Check for any recent product change notifications or end-of-life notices from the manufacturer. Ensure compatibility with standard surface-mount assembly processes.
Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes
Select this component for designs requiring a fixed 1.8V rail from higher input voltages up to 30V. Consider the SOT-25 package size constraints and thermal dissipation capabilities. Evaluate the need for the enable pin functionality versus simpler fixed-output alternatives. Verify capacitor selection aligns with low ESR requirements for stability.
Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context
The AP7383 series includes multiple fixed output voltage options such as 3.0V, 3.3V, 3.6V, 4.15V, 4.4V, and 5.0V.
