Description and Introduction

VERY LOW DROP VOLTAGE REGULATORS WITH INHIBIT The LD2981CU50TR is a low-dropout (LDO) voltage regulator manufactured by STMicroelectronics. Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Output Voltage:** 5.0V (fixed)  
- **Output Current:** 150mA  
- **Dropout Voltage:** 300mV (typical at full load)  
- **Input Voltage Range:** Up to 16V  
- **Quiescent Current:** 1.5µA (typical in OFF mode), 65µA (typical in ON mode)  
- **Line Regulation:** 0.015%/V (typical)  
- **Load Regulation:** 0.3mV/mA (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOT-23-5L  

### **Descriptions:**  
- The LD2981CU50TR is a low-quiescent-current LDO regulator designed for battery-powered applications.  
- It features very low dropout voltage and ultra-low ground current, making it suitable for power-sensitive devices.  
- Includes built-in protection features such as thermal shutdown and current limiting.  

### **Features:**  
- **Ultra-Low Quiescent Current:** Optimized for battery-operated applications.  
- **Low Dropout Voltage:** Ensures efficient operation even with low input voltages.  
- **Thermal Protection:** Prevents damage due to overheating.  
- **Current Limiting:** Protects the device and load from excessive current.  
- **Enable Pin:** Allows the regulator to be turned on/off via an external logic signal.  
- **Stable with Ceramic Capacitors:** Requires only a 1µF capacitor for stability.
