Description
The SGM2049XTRL20G/TR is a high-performance, low-dropout (LDO) voltage regulator from SGMICRO. Key features include:
- Input Voltage Range: 2.5V to 5.5V
- Output Voltage: Adjustable (0.8V to 5.0V) or fixed options
- Output Current: Up to 500mA
- Ultra-Low Dropout: 150mV at 300mA
- Low Quiescent Current: 40µA (typical)
- High PSRR: 70dB at 1kHz
- Protections: Overcurrent, thermal shutdown, and reverse current blocking
This LDO is designed for portable, battery-powered devices, IoT applications, and noise-sensitive systems. Its small DFN-1×1-4L package makes it ideal for space-constrained designs.
For detailed specs, refer to the datasheet from SGMICRO.
