AP7343D-28FS4-7R - High-Performance Low Dropout Voltage Regulator
The AP7343D-28FS4-7R from Diodes Incorporated is a precision low dropout (LDO) voltage regulator designed for applications requiring stable 2.8V output with excellent line and load regulation. This compact surface-mount device delivers up to 300mA output current while maintaining ultra-low quiescent current of just 60µA, making it ideal for battery-powered and energy-efficient designs.
Key Features & Benefits
- Fixed 2.8V Output: Precise voltage regulation for sensitive analog and digital circuits
- 300mA Output Current: Sufficient drive capability for microcontrollers, sensors, and RF modules
- Ultra-Low Dropout: Only 0.3V dropout at full load ensures efficient operation even with tight input margins
- Excellent PSRR: 75dB at 1kHz provides superior noise rejection for clean power delivery
- Comprehensive Protection: Built-in over-current, over-temperature, and short-circuit protection safeguards your system
- Compact X2-DFN1010-4 Package: Space-saving 4-pin exposed pad design for high-density PCB layouts
- Wide Operating Range: -40°C to 85°C temperature range suitable for industrial applications
Typical Applications
This LDO regulator is perfectly suited for portable electronics, IoT devices, wireless communication modules, battery-powered instruments, automotive electronics, and industrial control systems where stable, low-noise power is critical.
Performance Characteristics
The AP7343D-28FS4-7R excels in demanding power management applications with its exceptional electrical characteristics. The ultra-low dropout voltage of just 0.3V at maximum load enables efficient power conversion even when input voltage margins are tight, extending battery life in portable applications. With a quiescent current of only 60µA, this LDO minimizes standby power consumption, making it an excellent choice for always-on systems and sleep-mode circuits.
The device's impressive 75dB power supply rejection ratio (PSRR) at 1kHz effectively filters out input voltage noise and ripple, ensuring clean, stable output voltage for noise-sensitive analog circuits, precision sensors, and RF front-ends. Fast transient response and excellent load regulation maintain output voltage stability even during rapid load changes, protecting downstream components from voltage fluctuations.
Design Flexibility & Integration
Engineers will appreciate the AP7343D-28FS4-7R's simple external component requirements and integrated protection features. The enable pin provides convenient power sequencing and shutdown control, allowing designers to implement sophisticated power management schemes. Built-in thermal shutdown, current limiting, and short-circuit protection ensure robust operation and protect both the regulator and the powered circuitry from fault conditions.
The ultra-compact X2-DFN1010-4 package with exposed thermal pad measures just 1.0mm x 1.0mm, making it one of the smallest LDO packages available. This miniature footprint is ideal for space-constrained designs such as wearables, smartphones, IoT sensors, and other portable devices where board real estate is at a premium.
