Description and Introduction

Micropower, 150mA Low-Noise Ultra Low-Dropout CMOS Voltage Regulator The LP3985IBP-285 is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Output Voltage:** 2.85V (fixed)  
- **Output Current:** 150mA  
- **Dropout Voltage:** 150mV (typical) at 150mA load  
- **Input Voltage Range:** 2.5V to 6.0V  
- **Line Regulation:** 0.02% (typical)  
- **Load Regulation:** 0.1% (typical)  
- **Quiescent Current:** 75µA (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOT-23-5  

### **Descriptions:**
- The LP3985IBP-285 is a high-accuracy, low-power LDO regulator designed for battery-powered applications.  
- It provides stable voltage regulation with low noise and high PSRR (Power Supply Rejection Ratio).  
- Includes built-in protection features such as thermal shutdown and current limit.  

### **Features:**
- **Low Dropout Voltage:** Ensures efficient operation with minimal headroom.  
- **Low Quiescent Current:** Extends battery life in portable devices.  
- **High PSRR:** 70dB at 1kHz (typical), reducing noise in sensitive applications.  
- **Fast Transient Response:** Suitable for dynamic load conditions.  
- **Thermal Shutdown & Current Limit Protection:** Enhances device reliability.  
- **Stable with Ceramic Capacitors:** No need for additional ESR compensation.  

This information is based solely on the manufacturer's datasheet.
