Description and Introduction

VERY LOW DROP VOLTAGE REGULATORS WITH INHIBIT The LD2981CM28TR is a low-dropout (LDO) voltage regulator manufactured by STMicroelectronics. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Input Voltage Range:** Up to 16V  
- **Output Voltage:** 2.8V (fixed)  
- **Output Current:** 150mA  
- **Dropout Voltage:** 300mV (typical at full load)  
- **Quiescent Current:** 1.1µA (typical in OFF mode), 40µA (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 LD2981CM28TR is a low-quiescent-current LDO regulator designed for battery-powered applications.  
- It features very low dropout voltage and ultra-low power consumption, making it suitable for portable and energy-efficient devices.  
- The device includes thermal shutdown and current limit protection for enhanced reliability.  

### **Features:**
- **Ultra-Low Quiescent Current:** Ideal for battery-operated applications.  
- **Low Dropout Voltage:** Ensures efficient operation even with small input-output differentials.  
- **Thermal Shutdown Protection:** Prevents damage from overheating.  
- **Current Limitation:** Protects the device from excessive current.  
- **No External Components Required:** Simplifies design and reduces BOM cost.  
- **Fixed Output Voltage:** 2.8V with high accuracy (±2%).
