Description and Introduction

Micropower 150 mA Voltage Regulator in SOT-23 Package For Output Voltages [Less_Than_Or_Equal] 1.2V The LP2983IM5-1.2 is a low-dropout (LDO) voltage regulator manufactured by National Semiconductor (NSC). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Output Voltage:** 1.2V (fixed)  
- **Output Current:** 150mA  
- **Dropout Voltage:** 300mV (typical at 150mA load)  
- **Input Voltage Range:** 2.2V to 16V  
- **Quiescent Current:** 75µA (typical)  
- **Line Regulation:** 0.02%/V (typical)  
- **Load Regulation:** 0.05%/mA (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOT-23-5  

### **Descriptions:**
- The LP2983IM5-1.2 is a high-performance LDO regulator designed for low-power applications.  
- It provides a stable 1.2V output with low noise and high PSRR (Power Supply Rejection Ratio).  
- Suitable for battery-powered devices, portable electronics, and noise-sensitive applications.  

### **Features:**
- **Low Dropout Voltage:** Ensures efficient operation even with small input-output differentials.  
- **Low Quiescent Current:** Extends battery life in portable applications.  
- **Thermal Shutdown & Current Limit Protection:** Protects the device from overheating and overcurrent conditions.  
- **Stable with Low-ESR Capacitors:** Works with ceramic capacitors (≥1µF).  
- **High PSRR:** Reduces noise and ripple from the input supply.  

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