AP7365-33YG-13

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

The AP7365-33YG-13 is a fixed-output low dropout linear regulator manufactured by Diodes Incorporated. It provides a stable 3.3V output with a maximum current capacity of 600mA. The device operates within an input voltage range of 2V to 6V and features a typical quiescent current of 35µA. It utilizes the SOT89 package (Y variant) for surface mount installation. Key electrical characteristics include a dropout voltage of 300mV at full load, a power supply rejection ratio of 65dB at 1kHz, and a fast start-up time of 200µs. The unit supports an ambient operating temperature range from -40°C to +85°C.

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

Verify that the specific suffix 'YG' corresponds to the SOT89 package configuration required for your PCB layout. Confirm that the fixed 3.3V output aligns with your system voltage requirements. Ensure the component meets RoHS compliance standards if mandated by your manufacturing regulations. Check for any recent product change notifications regarding lead frame materials or bond wire composition before finalizing procurement.

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

Select this component when a fixed 3.3V rail is needed with up to 600mA load capability. The SOT89 package offers higher thermal dissipation compared to smaller footprints. Verify that the input voltage remains above 2V and does not exceed 6V under all operating conditions. Consider the 300mV dropout voltage to ensure sufficient headroom between input and output voltages at maximum load currents.
