Description and Introduction

Lithium-Ion Battery Charger Controller The LM3622 is a voltage regulator manufactured by National Semiconductor (NS). Below are the factual details about its specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 2.7V to 5.5V  
- **Output Voltage:** Adjustable (via external resistors) or fixed (1.8V, 2.5V, 2.8V, 3.0V, 3.3V)  
- **Output Current:** Up to 300mA  
- **Dropout Voltage:** 200mV (typical at 100mA load)  
- **Quiescent Current:** 35µA (typical)  
- **Shutdown Current:** <1µA  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Options:** SOT-23-5, Micro SMD  

### **Descriptions:**  
- The LM3622 is a low-dropout (LDO) voltage regulator designed for battery-powered applications.  
- It provides stable output voltage with low quiescent current, making it suitable for portable devices.  
- The device includes thermal shutdown and current limit protection.  

### **Features:**  
- Low dropout voltage (200mV typical at 100mA)  
- Ultra-low quiescent current (35µA typical)  
- Adjustable or fixed output voltage options  
- Thermal shutdown and current limit protection  
- Stable with low-ESR ceramic capacitors  
- Small form factor (SOT-23-5, Micro SMD packages)  

This information is based on the manufacturer's datasheet for the LM3622.
