Description and Introduction

100-MA ULTRA DROPOUT REGULATOR WITH SHUTDOWN The LP2981-50DBVR is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Output Voltage:** 5.0V (fixed)  
- **Output Current:** 150mA  
- **Dropout Voltage:** 300mV (typical) at 150mA load  
- **Input Voltage Range:** 2.5V to 16V  
- **Accuracy:** ±1.5% (over line, load, and temperature)  
- **Quiescent Current:** 80µA (typical)  
- **Package:** SOT-23-5 (DBV)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Line Regulation:** 0.02%/V (typical)  
- **Load Regulation:** 0.04%/mA (typical)  
- **Protection Features:** Thermal shutdown, current limit  

### **Descriptions:**
- The LP2981-50DBVR is a micropower LDO regulator designed for battery-powered applications.  
- It provides a stable 5.0V output with low noise and high PSRR (Power Supply Rejection Ratio).  
- Suitable for portable electronics, embedded systems, and power-sensitive applications.  

### **Features:**
- **Low Dropout Voltage:** Ensures efficient operation even with small input-output differentials.  
- **Low Quiescent Current:** Ideal for battery-powered devices.  
- **High PSRR:** 70dB at 1kHz (improves noise rejection).  
- **Thermal Shutdown & Current Limit Protection:** Enhances reliability.  
- **Stable with Low-ESR Capacitors:** Works with ceramic capacitors (≥1µF).  
- **Fast Transient Response:** Suitable for dynamic load conditions.  

This information is strictly based on the manufacturer's datasheet.
