Description and Introduction

Micropower 150 mA Low-Noise Ultra Low-Dropout Regulator in SOT-23 and micro SMD Packages The LP2985IM5-3.5 is a low-dropout (LDO) voltage regulator manufactured by National Semiconductor (NSC).  

### **Specifications:**  
- **Output Voltage:** 3.5V (fixed)  
- **Output Current:** 150mA  
- **Dropout Voltage:** 300mV (typical at full load)  
- **Input Voltage Range:** Up to 16V  
- **Low Quiescent Current:** 75µA (typical)  
- **Low Shutdown Current:** <1µA  
- **Accuracy:** ±2% over line, load, and temperature  
- **Package:** SOT-23-5  
- **Operating Temperature Range:** -40°C to +125°C  
- **Protection Features:** Thermal shutdown, current limit  

### **Descriptions and Features:**  
- Designed for battery-powered applications requiring stable voltage regulation.  
- Ultra-low dropout performance enhances efficiency.  
- Stable with low-ESR ceramic capacitors (≥1µF).  
- Includes an enable/shutdown pin for power management.  
- Suitable for portable electronics, instrumentation, and embedded systems.  

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