Description and Introduction

Ultra-Low Quiescent Current 3.3V Regulator The LM2936-3.3 is a low-dropout (LDO) voltage regulator manufactured by National Semiconductor (NS). Below are its specifications, descriptions, and features:

### **Specifications:**
- **Output Voltage:** 3.3V (fixed)  
- **Output Current:** Up to 50mA  
- **Dropout Voltage:** 340mV (typical at 50mA)  
- **Input Voltage Range:** 4V to 26V  
- **Quiescent Current:** 75µA (typical)  
- **Line Regulation:** 0.02% (typical)  
- **Load Regulation:** 0.3% (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package Options:** TO-92, SOT-223, SOIC-8  

### **Descriptions:**  
The LM2936-3.3 is a precision LDO voltage regulator designed for applications requiring stable and efficient power management. It is optimized for low-power systems and provides protection features such as reverse battery protection, thermal shutdown, and current limiting.

### **Features:**  
- **Low Quiescent Current:** Ensures minimal power loss in standby mode.  
- **Reverse Battery Protection:** Safeguards the regulator from damage due to reverse polarity.  
- **Thermal Shutdown:** Prevents overheating by shutting down at high temperatures.  
- **Current Limiting:** Protects against excessive load currents.  
- **Stable with Low-ESR Capacitors:** Works efficiently with ceramic or tantalum capacitors.  
- **Low Dropout Voltage:** Enhances efficiency in battery-powered applications.  

This information is based on the manufacturer's datasheet for the LM2936-3.3 by National Semiconductor (NS).
