AP7342D-2518FS6-7

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

The AP7342D-2518FS6-7 is a dual low-dropout regulator from Diodes Incorporated, packaged in an X2-DFN1212-6 footprint. It provides two fixed output voltages: Channel 1 delivers 2.5V and Channel 2 delivers 1.8V. The device guarantees an output current of 150mA per channel with a wide input voltage range of 1.7V to 5.25V. Key electrical specifications include a ripple rejection ratio of 75dB at 1kHz, a maximum dropout voltage of 0.34V at full load, and a quiescent current as low as 35µA. The 'D' suffix indicates the inclusion of auto-discharge resistors on the outputs.

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

Verify component authenticity through authorized Diodes Incorporated distributors or direct channels. Confirm RoHS compliance and lead-free status against current regulatory standards. Ensure ordering suffixes match specific package and discharge requirements. Validate datasheet revision compatibility before finalizing procurement contracts.

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

Select this component when dual isolated rails are required within a compact form factor. The D-suffix variant is necessary if automatic output discharge is needed for system safety. Verify that the 150mA current rating meets peak load demands. Consider thermal dissipation limits in dense PCB layouts due to the small package size.

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

This part belongs to the AP7342 series of dual LDO regulators designed for low-power handheld devices. It utilizes a CMOS process to achieve high accuracy and low quiescent current. The series supports various fixed voltage combinations within the 1.2V to 3.6V range, offering flexibility for different logic and analog supply needs.

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

Diodes Incorporated recommends using the AP7345D for new designs instead of the AP7342 series. Evaluate pin compatibility and electrical parameter equivalence when considering alternative single-source LDOs.
