Description and Introduction

Micropower 150 mA Low-Noise Ultra Low-Dropout Regulator in SOT-23 and micro SMD Packages The LP2985AITPX-1.8 is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (formerly National Semiconductor, NS).  

### **Specifications:**  
- **Output Voltage:** 1.8V (fixed)  
- **Output Current:** 150mA  
- **Dropout Voltage:** 300mV (typical at full load)  
- **Input Voltage Range:** 2.5V to 16V  
- **Accuracy:** ±1.5% (over line, load, and temperature)  
- **Low Quiescent Current:** 75µA (typical)  
- **Low Shutdown Current:** <1µA  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOT-23-5 (DBV)  

### **Features:**  
- **Ultra-Low Dropout Voltage** for extended battery life  
- **Low Noise & High PSRR** for noise-sensitive applications  
- **Thermal Shutdown & Current Limit Protection**  
- **Stable with Low-ESR Ceramic Capacitors** (≥1µF)  
- **Fast Transient Response** for dynamic loads  
- **Green (Pb-Free & RoHS Compliant)**  

### **Applications:**  
- Battery-powered devices  
- Portable electronics  
- RF and wireless systems  
- Post-regulation for switching supplies  

This regulator is designed for space-constrained, power-sensitive applications requiring stable voltage regulation.
