AP7344D-1818RH4-7

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

The AP7344D-1818RH4-7 is a dual-channel low-dropout regulator manufactured by Diodes Incorporated. It provides two independent fixed output voltages of 1.8V, each capable of delivering up to 300mA. The device operates with an input voltage range of 1.7V to 5.25V and features high ripple rejection of 75dB at 1kHz. It includes integrated enable controls for both channels and incorporates short-circuit protection. The component is housed in an X2-DFN1612-8 package.

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

Verify the specific ordering suffix RH4-7 to confirm the X2-DFN1612-8 package and tape-and-reel quantity. Confirm that the D suffix indicates the presence of internal auto-discharge resistors on the output channels. Ensure compatibility with RoHS 3 compliance requirements before finalizing procurement orders.

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

Select this component when a compact dual-rail solution is required for space-constrained designs. The 1.8V/1.8V configuration suits systems needing identical dual power rails. Consider the 300mA per channel limit and ensure adequate PCB copper area for thermal dissipation given the small footprint package dimensions.

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

This part belongs to the AP7344 family of dual LDO regulators designed for handheld electronics. It utilizes a CMOS process to achieve low dropout voltage and high accuracy. The datasheet explicitly states that the AP7344 is not recommended for new designs and suggests using the AP7345D as a replacement.

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

Diodes Incorporated recommends using the AP7345D instead of the AP7344 for new designs.
