Description and Introduction

Micropower, 150mA Low-Noise Ultra Low-Dropout CMOS Voltage Regulator The LP3985IM5X-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:** 150mA  
- **Dropout Voltage:** 120mV (typical) at 100mA load  
- **Input Voltage Range:** 2.5V to 6V  
- **Low Quiescent Current:** 75µA (typical)  
- **High PSRR:** 70dB at 1kHz  
- **Package:** SOT-23-5  
- **Operating Temperature Range:** -40°C to +125°C  
- **Protection Features:** Overcurrent and thermal shutdown  

### **Descriptions and Features:**  
- Ultra-low dropout voltage for extended battery life.  
- Stable with low-ESR ceramic capacitors (1µF or higher).  
- Low noise and high power supply ripple rejection (PSRR).  
- Fast transient response for portable applications.  
- Designed for space-constrained applications due to its small SOT-23-5 package.  
- Suitable for battery-powered devices, wireless systems, and portable electronics.  

This regulator is optimized for efficiency and reliability in power-sensitive designs.
