Description and Introduction

MOSFET LDO Driver/Controller The LP2975IMM-3.3 is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (formerly National Semiconductor, NS).  

### **Specifications:**  
- **Output Voltage:** 3.3V (fixed)  
- **Output Current:** 500mA  
- **Dropout Voltage:** 300mV (typical at 500mA load)  
- **Input Voltage Range:** 2.7V to 7V  
- **Accuracy:** ±1.5% (over line, load, and temperature)  
- **Low Quiescent Current:** 75µA (typical)  
- **Package:** 8-Pin SOIC (MM8)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Protection Features:** Overcurrent, Overtemperature, Reverse Battery  
- **Enable Pin:** Yes (logic-controlled shutdown)  

### **Descriptions and Features:**  
- Designed for battery-powered applications requiring stable voltage regulation.  
- Low dropout voltage ensures efficient operation with minimal input-output differential.  
- Stable with low-ESR ceramic capacitors.  
- Thermal shutdown and current limit protection enhance reliability.  
- Logic-controlled enable pin allows for power management.  
- Suitable for portable devices, embedded systems, and power-sensitive applications.
