Description and Introduction

ERY LOW DROP AND LOW NOISE VOLTAGE REGULATO WITH INHIBIT FUNCTION The LD2985BM18R is a low-dropout (LDO) voltage regulator manufactured by STMicroelectronics (ST).  

### **Specifications:**  
- **Output Voltage:** 1.8V (fixed)  
- **Maximum Output Current:** 500mA  
- **Dropout Voltage:** 300mV (typical at 500mA load)  
- **Input Voltage Range:** 2.5V to 16V  
- **Low Quiescent Current:** 40µA (typical)  
- **Low Standby Current:** 0.1µA (typical)  
- **Output Accuracy:** ±2% (over line, load, and temperature)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOT-223-4L  

### **Descriptions:**  
- Designed for battery-powered applications  
- Features very low dropout voltage and low quiescent current  
- Includes thermal shutdown and current limit protection  
- Stable with low-ESR ceramic capacitors (≥1µF)  

### **Features:**  
- **Low Dropout Voltage:** Ensures efficient regulation even with small input-output differentials.  
- **Ultra-Low Quiescent Current:** Extends battery life in portable applications.  
- **Thermal Protection:** Prevents damage from overheating.  
- **Current Limiting:** Protects against short circuits and overloads.  
- **Wide Input Voltage Range:** Suitable for various power sources.  
- **No External Components Required:** Only a small output capacitor is needed for stability.  

This regulator is commonly used in consumer electronics, industrial applications, and battery-powered devices.
