Description and Introduction

150-mA, 3.3-V, Low-Noise LDO w/ In-Rush Current Ctrl for USB Applications The TPS78833DBVRG4 is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Output Voltage:** 3.3V (fixed)  
- **Output Current:** 1A  
- **Dropout Voltage:** 175mV (typical) at 1A  
- **Input Voltage Range:** 2.5V to 6.5V  
- **Accuracy:** ±2% (over line, load, and temperature)  
- **Quiescent Current:** 85µA (typical)  
- **PSRR (Power Supply Rejection Ratio):** 65dB at 1kHz  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOT-23-5 (DBV)  

### **Descriptions:**
- The TPS78833DBVRG4 is a high-performance LDO regulator designed for applications requiring low noise, high PSRR, and fast transient response.  
- It features a low dropout voltage, making it suitable for battery-powered devices.  
- The device includes thermal shutdown and current limit protection for enhanced reliability.  

### **Features:**
- **High Efficiency:** Low dropout voltage minimizes power loss.  
- **Low Noise:** Optimized for noise-sensitive applications.  
- **Fast Transient Response:** Ensures stable output under dynamic load conditions.  
- **Thermal & Overcurrent Protection:** Safeguards against overheating and excessive current.  
- **Small Form Factor:** SOT-23-5 package saves board space.  
- **Enable Pin:** Allows for power management control.  

This LDO is commonly used in portable electronics, industrial systems, and communication devices.
