AP7365-18WG-7

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

The AP7365-18WG-7 is a fixed-output low dropout linear regulator manufactured by Diodes Incorporated. It provides a regulated 1.8V output with a maximum continuous current 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 SOT25 surface-mount package. Key electrical characteristics include a typical power supply rejection ratio (PSRR) of 65dB at 1kHz, a fast start-up time of 200µs, and a maximum dropout voltage of 370mV at full load for outputs below 2.5V.

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

Verify that the component matches the specified SOT25 package and 1.8V fixed output configuration. Confirm RoHS compliance and green manufacturing status as documented. Ensure the ordering suffix corresponds to the required tape and reel packaging quantity. Cross-reference the manufacturer part number against official Diodes Incorporated documentation to validate authenticity and revision level before integration into production designs.

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

Select this regulator when a stable 1.8V rail is required for loads up to 600mA. The wide input voltage range accommodates single-cell battery systems or standard 3.3V logic rails. The low quiescent current makes it suitable for battery-powered portable devices where standby power consumption must be minimized. Verify that the PCB layout supports the thermal requirements associated with the SOT25 package under expected operating conditions.

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