Description and Introduction

Ultra Low Noise, High PSRR, Fast RF, Low-Enable, 100mA Low Dropout Regulator The TPS79101DBVRQ1 is a low-dropout (LDO) linear voltage regulator manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Output Voltage:** 1.0V (fixed)  
- **Output Current:** 100mA  
- **Dropout Voltage:** 110mV (typical) at 100mA load  
- **Input Voltage Range:** 1.7V to 5.5V  
- **Accuracy:** ±2% (over line, load, and temperature)  
- **Quiescent Current:** 17µA (typical)  
- **Package:** SOT-23-5 (DBV)  
- **Operating Temperature Range:** -40°C to +125°C  
- **PSRR:** 75dB at 1kHz  

### **Descriptions:**  
- **Automotive Qualified:** AEC-Q100 Grade 1  
- **Low Noise:** Optimized for noise-sensitive applications  
- **Stable with Ceramic Capacitors:** Requires only 1µF (minimum) on output  

### **Features:**  
- **Low Dropout:** Enables operation with very small headroom  
- **Low IQ:** Suitable for battery-powered applications  
- **Thermal Shutdown & Current Limit Protection:** Enhances reliability  
- **Fast Start-Up Time:** ~50µs (typical)  
- **Reverse Current Protection:** Prevents damage from reverse polarity  

This LDO is designed for automotive and industrial applications requiring stable, low-noise voltage regulation.
