Description and Introduction

Micropower 150 mA Low-Noise Ultra Low-Dropout Regulator in SOT-23 and micro SMD Packages The LP2985IM5X-3.1 is a low-dropout (LDO) voltage regulator manufactured by **NATIONAL SEMICONDUCTOR** (now part of Texas Instruments).  

### **Specifications:**  
- **Output Voltage:** 3.1V (fixed)  
- **Output Current:** 150mA  
- **Dropout Voltage:** 300mV (typical at full load)  
- **Input Voltage Range:** 2.5V to 16V  
- **Low Quiescent Current:** 75µA (typical)  
- **Package:** SOT-23-5 (Miniature 5-Pin Package)  
- **Accuracy:** ±1.5% (over line, load, and temperature)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Protection Features:**  
  - Thermal shutdown  
  - Current limit  

### **Descriptions & Features:**  
- Designed for battery-powered applications requiring stable voltage regulation.  
- Ultra-low dropout performance suitable for low-input voltage conditions.  
- Stable with low-ESR ceramic capacitors (≥1µF).  
- Low noise and high PSRR (Power Supply Rejection Ratio).  
- Ideal for portable electronics, wireless devices, and embedded systems.  

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