AP7343D-18FS4-7A - High-Performance Low Dropout Voltage Regulator
The AP7343D-18FS4-7A from Diodes Incorporated is a precision 300mA low dropout (LDO) voltage regulator designed for demanding applications requiring stable 1.8V output. This advanced regulator combines ultra-low quiescent current consumption with excellent power supply rejection ratio, making it ideal for battery-powered devices, portable electronics, and noise-sensitive circuits.
Key Features & Benefits
- Ultra-Low Quiescent Current: Only 60µA typical consumption extends battery life in portable applications
- Excellent PSRR Performance: 75dB at 1kHz ensures clean output voltage even with noisy input supplies
- Low Dropout Voltage: 0.39V @ 300mA maximizes efficiency and allows operation with lower input voltages
- Comprehensive Protection: Built-in over-current, over-temperature, and short-circuit protection safeguards your circuit
- Compact Footprint: X2-DFN1010-4 package (4-XDFN Exposed Pad) saves valuable PCB space
- Wide Operating Range: -40°C to 85°C temperature range suitable for industrial applications
Applications & Use Cases
- Battery-Powered Devices: Smartphones, tablets, and portable medical equipment requiring extended battery life
- Wearable Electronics: Fitness trackers, smartwatches, and health monitoring devices
- IoT & Wireless Sensors: Low-power sensor nodes, smart home devices, and remote monitoring systems
- Audio & RF Circuits: High-fidelity audio equipment and RF modules requiring ultra-low noise power supplies
- Industrial Control: Process control systems, PLCs, and automation equipment operating in harsh environments
- Consumer Electronics: Digital cameras, gaming devices, and multimedia players
Design Advantages
The AP7343D-18FS4-7A offers exceptional performance for space-constrained designs. Its ultra-low quiescent current of just 60µA makes it perfect for always-on applications where battery life is critical. The excellent 75dB PSRR at 1kHz effectively filters out input voltage ripple and noise, ensuring stable operation even in electrically noisy environments. With a low dropout voltage of only 0.39V at full 300mA load, this regulator maintains regulation even when input voltage approaches the output voltage, maximizing usable battery capacity.
