AP7332-2833FM-7

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

The AP7332-2833FM-7 is a dual fixed-output low dropout linear regulator manufactured by Diodes Incorporated. It provides two independent output channels with voltages of 2.8V and 3.3V, each capable of delivering up to 300mA. The device operates within an input voltage range of 2V to 6V and features a typical quiescent current of 60µA. It includes integrated protection mechanisms such as current limit, short circuit protection, and thermal shutdown. The component is housed in a DFN2018-6 package.

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

Verify the specific ordering suffix FM-7 confirms the DFN2018-6 package and tape & reel packaging format. Confirm that the 2833 designation matches the required 2.8V and 3.3V output combination. Check datasheet revision history for any updates to electrical characteristics or pin assignments before finalizing procurement specifications.

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

Select this component when dual isolated rails are required from a single input source. Ensure the input voltage remains within the 2V to 6V operating range. Verify that the PCB layout accommodates the DFN2018-6 footprint and thermal requirements. Consider the 60µA quiescent current impact on total system power consumption during standby modes.
