SY6280AAAC

The SY6280AAAC is a highly efficient, low-dropout (LDO) linear voltage regulator designed for portable and battery-powered applications. It features an ultra-low quiescent current (typically 1.5μA) and a low dropout voltage (e.g., 200mV at 300mA), making it ideal for extending battery life in devices like IoT sensors, wearables, and wireless modules.
Key specifications:
- Input voltage range: 2.0V–5.5V
- Output voltage: Adjustable (0.8V–5.0V) or fixed options
- Output current: Up to 300mA
- High PSRR (60dB @1kHz) for stable performance
- Thermal and overcurrent protection
Its compact SOT-23-5 package and minimal external component requirements simplify PCB design. The SY6280AAAC balances efficiency, size, and reliability, making it a strong choice for power-sensitive applications.
