Description and Introduction

ULTRA LOW DROP-LOW NOISE BICMOS VOLTAGE REGULATORS LOW ESR CAPACITORS COMPATIBLE The LD3985G30R is a low-dropout (LDO) voltage regulator manufactured by STMicroelectronics. Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Output Voltage:** 3.0V (fixed)  
- **Input Voltage Range:** 2.5V to 6.0V  
- **Dropout Voltage:** 200mV (typical) at 150mA load  
- **Maximum Output Current:** 150mA  
- **Line Regulation:** ±0.2% (typical)  
- **Load Regulation:** ±0.4% (typical)  
- **Quiescent Current:** 50µA (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOT-23-5  

### **Descriptions:**  
- The LD3985G30R is a low-noise, low-dropout linear regulator designed for battery-powered applications.  
- It provides a stable 3.0V output with high accuracy (±2% over line, load, and temperature variations).  
- The device includes features like thermal shutdown and current limiting for protection.  

### **Features:**  
- **Low Dropout Voltage:** Ensures efficient operation even with small input-output differentials.  
- **Low Quiescent Current:** Ideal for power-sensitive applications.  
- **Low Noise:** Suitable for noise-sensitive circuits like RF and analog components.  
- **Thermal Shutdown & Current Limit Protection:** Enhances reliability under fault conditions.  
- **Stable with Low-ESR Ceramic Capacitors:** Reduces external component count.
