- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** TO-263 (D2PAK), TO-220, SOIC-8  

### **Descriptions:**  
The LP2954AIS is a precision voltage regulator with low dropout voltage, designed for battery-powered applications. It includes features such as error flag output for low-voltage detection, thermal shutdown, and current limiting.  

### **Features:**  
- Low dropout voltage (380mV typical at 100mA)  
- Very low quiescent current (75µA typical)  
- Adjustable or fixed output voltage options  
- Thermal shutdown and current limit protection  
- Error flag output for undervoltage warning  
- Stable with low-ESR capacitors (≥1µF)  
- Low noise operation  

This information is based on the manufacturer's datasheet. For detailed electrical characteristics and application notes, refer to the official documentation.
