Description and Introduction

Ultra Low-Power 100-mA Low-Dropout (LDO) Line Regulators The TPS76912DBVR is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Output Voltage:** 1.2V (fixed)  
- **Input Voltage Range:** 2.7V to 10V  
- **Dropout Voltage:** 340mV (typical at 100mA load)  
- **Output Current:** Up to 100mA  
- **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 (Power Supply Rejection Ratio):** 60dB at 1kHz  

### **Descriptions:**  
The TPS76912DBVR is a low-power, low-dropout linear regulator designed for battery-powered applications. It provides a stable 1.2V output with low quiescent current, making it suitable for portable and power-sensitive devices.  

### **Features:**  
- Ultra-low quiescent current (17µA typical)  
- Low dropout voltage (340mV at 100mA)  
- Stable with low-ESR ceramic capacitors (≥1µF)  
- Thermal shutdown and current limit protection  
- Small SOT-23-5 package for space-constrained applications  
- High PSRR for noise-sensitive circuits  

This regulator is commonly used in battery-powered systems, portable electronics, and embedded applications requiring a stable 1.2V supply.
