AP7342D-3030FS6-7

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

The AP7342D-3030FS6-7 is a dual low-dropout regulator from Diodes Incorporated, featuring two independent channels with fixed 3.0V outputs. It operates within an input voltage range of 1.7V to 5.25V and guarantees a continuous output current of 150mA per channel. The device incorporates high ripple rejection of 75dB at 1kHz and maintains a low output noise of 60µVrms across the 10Hz to 100kHz bandwidth. Quiescent current is specified at 35µA under single-channel operation. The component utilizes an X2-DFN1212-6 package and includes integrated enable controls for each channel.

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

Verify the specific ordering suffix to confirm the presence of internal auto-discharge resistors, as indicated by the 'D' designation in the part number. Confirm compliance with RoHS directives and halogen-free requirements during sourcing. Ensure that the X2-DFN1212-6 package dimensions align with the target PCB footprint constraints. Validate that the selected components meet the required operating temperature range specifications for the intended deployment environment.

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

Select this component when dual isolated rails are required from a single input source. The 3.0V fixed output configuration eliminates the need for external resistor networks. Consider the low quiescent current for battery-operated applications requiring extended standby times. Evaluate the dropout voltage characteristics against the minimum available input voltage to ensure regulation stability under varying load conditions.

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

This device belongs to the AP7342 series of dual LDO regulators manufactured by Diodes Incorporated. It shares architectural similarities with other members of the family but differs in specific output voltage configurations and discharge features. The series targets portable electronics requiring compact footprints and efficient power management solutions.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

The datasheet explicitly recommends using the AP7345D instead of the AP7342 for new designs. Verify pin compatibility and electrical parameter alignment before substituting with other dual LDOs from different manufacturers.
