AP7331-10WG-7

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

The AP7331-10WG-7 is a fixed-output linear regulator from Diodes Incorporated, providing a stable 1.0V output with a maximum load current of 300mA. It operates within an input voltage range of 2V to 6V and features a typical quiescent current of 65µA across the full load spectrum. The device incorporates an enable pin for power management control and delivers excellent line and load transient response. It maintains stability using low ESR ceramic capacitors as small as 1µF. Integrated protection mechanisms include current limiting, short-circuit protection, and thermal shutdown to safeguard against fault conditions.

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

Verify that the ordering suffix WG-7 corresponds to the SOT-25 package and tape-and-reel packaging format. Confirm the '10' designation matches the required 1.0V fixed output voltage. Ensure compliance with RoHS directives and check for the absence of bromine and antimony in the molding compound. Validate the manufacturer part number against official Diodes Incorporated documentation before finalizing procurement orders.

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

Select this component when a fixed 1.0V rail is required with up to 300mA load capability. It is suitable for applications needing fast transient response and ultra-low startup times. Verify that the input voltage remains within the 2V to 6V operating range. Ensure the design accommodates the recommended 1µF minimum ceramic output capacitor for stability. Consider the SOT-25 package constraints regarding thermal dissipation and PCB layout requirements.
