Description and Introduction

200mA, Low Quiescent Current, Ultra-Low Noise, High PSRR Low Dropout Linear Regulator 5-DSBGA -40 to 125 The TPS79901YZUT is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (TI). Here are its key specifications, descriptions, and features:  

### **Specifications:**  
- **Output Voltage:** 1.8V (fixed)  
- **Output Current:** 200mA  
- **Dropout Voltage:** 175mV (typical) at 200mA  
- **Input Voltage Range:** 2.5V to 6.5V  
- **Accuracy:** ±2% (over line, load, and temperature)  
- **Quiescent Current:** 17µA (typical)  
- **Package:** 5-pin SOT-23 (YZU)  
- **Operating Temperature Range:** -40°C to +125°C  

### **Descriptions:**  
- The TPS79901YZUT is a low-noise, low-dropout linear regulator designed for battery-powered applications.  
- It provides stable voltage regulation with minimal power loss.  
- Features enable/disable control for power management.  

### **Features:**  
- **Low Dropout Voltage:** Ensures efficient operation with small input-output differentials.  
- **Low Noise:** Optimized for noise-sensitive applications.  
- **Low Quiescent Current:** Extends battery life in portable devices.  
- **Thermal Shutdown & Current Limit Protection:** Safeguards against overheating and overcurrent.  
- **Stable with Ceramic Capacitors:** Works with small, low-cost capacitors (≥1µF).
