Description and Introduction

100-MA ULTRA DROPOUT REGULATOR WITH SHUTDOWN The LP2981A-33DBVR is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Output Voltage:** 3.3V (fixed)  
- **Output Current:** 100mA  
- **Dropout Voltage:** 300mV (typical at 100mA load)  
- **Input Voltage Range:** 2.5V to 16V  
- **Low Quiescent Current:** 75µA (typical)  
- **Low Noise:** 30µVRMS (10Hz to 100kHz)  
- **High PSRR:** 65dB at 1kHz  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOT-23-5 (DBV)  

### **Descriptions and Features:**  
- **Ultra-Low Dropout:** Ensures stable operation even with small input-output differentials.  
- **Low Quiescent Current:** Ideal for battery-powered applications.  
- **Stable with Ceramic Capacitors:** Requires only a 1µF output capacitor for stability.  
- **Thermal Shutdown & Current Limit Protection:** Protects the device from overheating and overcurrent conditions.  
- **Low Noise & High PSRR:** Suitable for noise-sensitive applications like RF and precision analog circuits.  
- **Fixed Output Voltage:** No external resistors needed for voltage setting.  

This LDO is commonly used in portable electronics, medical devices, and precision analog systems.
