Description and Introduction

Ultra Low Noise, High PSRR, Fast RF, Low-Enable, 100mA Low Dropout Regulator The TPS79133DBVTG4 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:** 150mA  
- **Dropout Voltage:** 110mV (typical at 150mA load)  
- **Input Voltage Range:** 2.7V to 5.5V  
- **Quiescent Current:** 17µA (typical)  
- **PSRR (Power Supply Rejection Ratio):** 75dB at 1kHz  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOT-23-5 (DBV)  

### **Descriptions:**
- The TPS79133DBVTG4 is a low-noise, high-PSRR LDO regulator designed for battery-powered and noise-sensitive applications.  
- It provides a stable 3.3V output with low dropout voltage and ultra-low quiescent current, making it suitable for portable devices.  
- Features a fast transient response and includes built-in protection circuits such as thermal shutdown and current limit.  

### **Features:**
- **Ultra-Low Noise:** 30µVRMS (10Hz to 100kHz)  
- **High PSRR:** 75dB at 1kHz  
- **Low Dropout Voltage:** 110mV (typical at 150mA)  
- **Low Quiescent Current:** 17µA (typical)  
- **Thermal Shutdown & Current Limit Protection**  
- **Stable with Low-ESR Ceramic Capacitors (≥1µF)**  
- **Small SOT-23-5 Package for Space-Constrained Applications**  

This device is commonly used in portable electronics, medical devices, and precision analog systems requiring stable, low-noise power supplies.
