The AP7345D-1818RH4-7 is a dual-channel, fixed-output LDO regulator from Diodes Incorporated. It delivers two independent 1.8V rails, each capable of sourcing 300mA. With a low dropout voltage of 0.39V and a quiescent current of just 140 μA, it balances efficiency with clean, stable power. Its high PSRR of 75dB at 1kHz makes it suitable for noise-sensitive applications. The compact X2-DFN1612-8 package is ideal for space-constrained designs.
- Dual Independent Outputs: Two 300mA channels in one package save board space and simplify dual-rail designs.
- High PSRR (75dB @ 1kHz): Effectively filters power supply noise, ensuring clean output for sensitive analog and RF circuits.
- Low Dropout (0.39V @ 300mA): Maintains regulation even with small input-to-output voltage margins, improving efficiency in battery applications.
- Compact X2-DFN1612-8 Package: Minimizes PCB footprint, ideal for portable and wearable electronics.
Dual-Rail Sensor Power
Power two separate 1.8V sensors or ADCs from a single LDO, ensuring matched voltage rails with minimal noise for accurate analog readings.
Battery-Powered Wearables
The low 140 μA quiescent current and dual outputs make it ideal for powering both a microcontroller and RF transceiver in compact wearables, extending battery life.
Camera Module Supply
Provide clean, stable 1.8V to image sensors and autofocus drivers, with 75dB PSRR at 1kHz to reject power supply noise and prevent image artifacts.
Portable Audio DACs
Use the dual outputs to power analog and digital sections of a DAC separately, reducing crosstalk and improving signal-to-noise ratio.
IoT Edge Nodes
Power a 1.8V logic rail and a 1.8V RF rail from one compact package, simplifying PCB layout in space-constrained IoT modules.
FPGA Core and I/O
Supply both core and I/O voltages at 1.8V with independent 300mA channels, ensuring stable operation during high-speed switching.
