Description and Introduction

Micropower, 150mA Low-Noise Ultra Low-Dropout CMOS Voltage Regulator The LP3985IBL-3.0 is a low-dropout (LDO) voltage regulator manufactured by National Semiconductor (NS).  

### **Specifications:**  
- **Output Voltage:** 3.0V (fixed)  
- **Output Current:** 150mA  
- **Dropout Voltage:** 300mV (typical) at full load  
- **Input Voltage Range:** 2.5V to 6.0V  
- **Low Quiescent Current:** 75µA (typical)  
- **High PSRR (Power Supply Rejection Ratio):** 60dB at 1kHz  
- **Low Noise:** 30µVRMS (typical)  
- **Thermal Shutdown & Current Limit Protection**  
- **Package:** SOT-23-5  

### **Descriptions & Features:**  
- Designed for battery-powered and portable applications.  
- Provides stable output with low dropout voltage.  
- Includes thermal shutdown and current limit protection for enhanced reliability.  
- Low quiescent current extends battery life.  
- High PSRR ensures stable performance in noisy environments.  
- Suitable for powering microcontrollers, RF modules, and other sensitive electronics.  

This regulator is optimized for space-constrained applications due to its small SOT-23-5 package.
