Description and Introduction

Micropower 150 mA Low-Noise Ultra Low-Dropout Regulator in SOT-23 and micro SMD Packages The LP2985AITPX-3.3 is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (formerly National Semiconductor, NS).  

### **Key Specifications:**  
- **Output Voltage:** 3.3V (fixed)  
- **Input Voltage Range:** 2.5V to 16V  
- **Output Current:** 150mA  
- **Dropout Voltage:** 300mV (typical at 150mA load)  
- **Accuracy:** ±1.5% (over line, load, and temperature)  
- **Quiescent Current:** 75µA (typical)  
- **Low Noise:** 30µVRMS (10Hz to 100kHz)  
- **Package:** SOT-23-5 (DBV)  
- **Operating Temperature Range:** -40°C to +125°C  

### **Features:**  
- Ultra-low dropout voltage  
- Low quiescent current  
- Stable with low-ESR ceramic capacitors (≥1µF)  
- Thermal shutdown and current limit protection  
- Reverse battery protection  
- Fast transient response  

This regulator is designed for battery-powered and noise-sensitive applications, such as portable electronics and precision analog circuits.  

(Note: Texas Instruments acquired National Semiconductor in 2011, so the part may now be listed under TI's product line.)
