Description and Introduction

Low Noise, Low Iq, 150-mA Low Dropout Linear Regulator with Adjustable Soft-Start 5-SOT-23 0 to 70 The TPS78833DBVTG4 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 (maximum)  
- **Dropout Voltage:** 175mV (typical at 1A load)  
- **Input Voltage Range:** 2.5V to 6.5V  
- **Accuracy:** ±2% (over line, load, and temperature)  
- **Quiescent Current:** 85µA (typical)  
- **PSRR (Power Supply Rejection Ratio):** 60dB (at 1kHz)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOT-23-5 (DBV)  

### **Descriptions:**  
- The TPS78833DBVTG4 is a high-performance, low-noise, low-dropout linear regulator designed for power-sensitive applications.  
- It provides a stable 3.3V output with excellent transient response and thermal performance.  
- Suitable for battery-powered devices, portable electronics, and noise-sensitive analog circuits.  

### **Features:**  
- **Low Dropout:** Enables operation with very small headroom voltage.  
- **Low Noise:** Optimized for noise-sensitive applications.  
- **Fast Transient Response:** Maintains stable output under load changes.  
- **Thermal and Overcurrent Protection:** Includes built-in safeguards.  
- **Stable with Low-ESR Capacitors:** Works with ceramic capacitors (≥1µF).  
- **Enable Pin:** Allows for power management control.  

This information is based on TI's official datasheet for the TPS78833DBVTG4.
