- **Quiescent Current:** 85µA (typical)  
- **Shutdown Current:** 1µA (typical)  
- **Operating Junction Temperature Range:** -40°C to +125°C  
- **Package:** SOT-223  

### **Descriptions:**  
The TPS77801D is a low-dropout linear regulator designed for applications requiring high efficiency and low power dissipation. It provides a fixed 1.8V output with high accuracy and stability, making it suitable for battery-powered devices, portable electronics, and embedded systems.  

### **Features:**  
- **Low Dropout Voltage:** Ensures efficient operation even with small input-output differentials.  
- **Thermal and Overcurrent Protection:** Safeguards the device from damage due to excessive heat or current.  
- **Low Quiescent Current:** Enhances battery life in portable applications.  
- **Stable with Low-ESR Capacitors:** Works reliably with ceramic output capacitors.  
- **Fast Transient Response:** Maintains stable output under dynamic load conditions.  
- **Enable Pin (SHDN):** Allows for power-saving shutdown mode.  

This information is based solely on the manufacturer's datasheet and technical documentation.
