Description and Introduction

VERY LOW DROP AND LOW NOISE VOLTAGE REGULATO WITH INHIBIT FUNCTION The LD2982BM33R is a low-dropout (LDO) voltage regulator manufactured by STMicroelectronics. Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Output Voltage:** 3.3V (fixed)  
- **Input Voltage Range:** Up to 16V  
- **Dropout Voltage:** 300mV (typical) at 150mA load  
- **Output Current:** Up to 300mA  
- **Quiescent Current:** 40µA (typical)  
- **Line Regulation:** 0.2mV (typical)  
- **Load Regulation:** 3mV (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOT-23-5L  

### **Descriptions:**  
- The LD2982BM33R is a low quiescent current LDO regulator designed for battery-powered applications.  
- It provides stable voltage output with low noise and high PSRR (Power Supply Rejection Ratio).  
- Includes built-in protection features such as thermal shutdown and current limiting.  

### **Features:**  
- **Low Dropout Voltage:** Ensures efficient operation even with small input-output differentials.  
- **Very Low Quiescent Current:** Ideal for power-sensitive applications.  
- **High PSRR:** 70dB at 1kHz (improves noise rejection).  
- **Thermal Protection:** Prevents damage from overheating.  
- **Short-Circuit Protection:** Safeguards the regulator during fault conditions.  
- **Low ESR Capacitor Compatible:** Works with ceramic capacitors (≥1µF).  

This regulator is commonly used in portable electronics, IoT devices, and automotive applications.
