### **Specifications:**
- **Output Voltage:** Adjustable (1.24V to 5.5V)  
- **Output Current:** 500mA  
- **Dropout Voltage:** 300mV (typical at 500mA)  
- **Input Voltage Range:** 2.5V to 6.0V  
- **Accuracy:** ±1.5% (over line, load, and temperature)  
- **Quiescent Current:** 75µA (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SC-70-5 (SOT-23-5)  

### **Descriptions:**
- The SC431LCSK-2TRT is a low-power, high-performance LDO regulator designed for battery-powered and portable applications.  
- It features low dropout voltage, low quiescent current, and excellent line/load regulation.  
- The adjustable output voltage is set using an external resistor divider.  

### **Features:**
- **Low Dropout Voltage:** Ensures efficient operation with minimal headroom.  
- **Low Quiescent Current:** Extends battery life in portable applications.  
- **Stable with Low-ESR Capacitors:** Works with ceramic capacitors (≥1µF).  
- **Thermal Shutdown & Current Limit Protection:** Protects the device from overheating and overcurrent.  
- **Fast Transient Response:** Suitable for dynamic load conditions.  
- **RoHS Compliant & Halogen-Free:** Meets environmental standards.
