Description and Introduction

5V Micropower Low-Dropout Voltage Regulator The LP2954IS is a low-dropout voltage regulator manufactured by National Semiconductor (NSC). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Output Voltage:** Adjustable (1.24V to 29V) or fixed (5V, 3.3V, 3V, etc.)  
- **Output Current:** Up to 250mA  
- **Dropout Voltage:** 380mV (typical at 100mA load)  
- **Input Voltage Range:** Up to 30V  
- **Line Regulation:** 0.03% (typical)  
- **Load Regulation:** 0.1% (typical)  
- **Quiescent Current:** 75µA (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOIC-8  

### **Descriptions:**
- The LP2954IS is a precision voltage regulator with low dropout voltage, designed for battery-powered and low-power applications.  
- It includes features like thermal shutdown, current limiting, and reverse battery protection.  
- The adjustable version uses an external resistor divider to set the output voltage.  

### **Features:**
- Low dropout voltage (380mV at 100mA)  
- Very low quiescent current (75µA typical)  
- Thermal shutdown and current limit protection  
- Reverse battery protection  
- Stable with low-ESR capacitors  
- Adjustable or fixed output voltage options  
- High accuracy (±1% over temperature)  

This information is based on the manufacturer's datasheet for the LP2954IS.
