AP7342D-1833FS6-7

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

The AP7342D-1833FS6-7 is a dual low-dropout regulator manufactured by Diodes Incorporated. It provides two fixed output voltages of 1.8V and 3.3V with a guaranteed output current of 150mA per channel. The device operates within an input voltage range of 1.7V to 5.25V and features a ripple rejection of 75dB at 1kHz. Quiescent current is typically 35µA, while output noise is 60µVrms from 10Hz to 100kHz. It utilizes an X2-DFN1212-6 package and includes integrated enable inputs for each channel.

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

Verify the specific ordering suffix FS6-7 to confirm the X2-DFN1212-6 package and tape-and-reel packing quantity. Confirm that the D suffix indicates the presence of auto-discharge functionality on the outputs. Ensure compatibility with the required input voltage range and load transient response specifications before finalizing procurement.

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

Select this component when a compact dual LDO solution is required for portable electronics. The X2-DFN1212-6 package supports dense PCB layouts. Verify that the 150mA output current per channel meets the system requirements. Consider the 1.7V minimum input voltage for battery-powered applications. Check if the specific 1.8V/3.3V combination matches the target design needs.

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

The AP7342 series consists of dual high PSRR low-noise LDOs based on CMOS process technology. This specific part belongs to the AP7342 family, which offers fixed output voltages ranging from 1.2V to 3.6V. The datasheet notes that the AP7342 is not recommended for new designs and suggests using the AP7345D instead.
