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

Verify the specific output voltage suffix (D18 indicates 1.8 V) against design requirements. Confirm the SC-82AB-4 package compatibility with PCB footprint. Ensure input voltage remains within the 1.5 V to 5.5 V operational limits. Check thermal dissipation capabilities relative to the 400 mW power rating under expected load conditions.

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

Select this component when ultra-low standby current is critical for battery life extension. The 200 mA output capacity suits moderate load applications. The fixed 1.8 V output eliminates external resistor networks. Consider the SC-82AB-4 package size constraints during layout planning. Verify that the 1.5 V minimum input voltage aligns with the source supply characteristics.

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

This part belongs to the S-1313 series of ultra-low IQ linear regulators from ABLIC. The series emphasizes minimal current drain while maintaining stable output voltages.
