Description and Introduction

200mA Low Quiescent Current, Ultra-Low Noise, High PSRR LDO The TPS79933DDCR 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:** 200mA  
- **Dropout Voltage:** 110mV (typical at 200mA)  
- **Input Voltage Range:** 2.7V to 5.5V  
- **Accuracy:** ±2% (over line, load, and temperature)  
- **Quiescent Current:** 17µA (typical)  
- **Package:** SOT-23-5 (DDC)  
- **Operating Temperature Range:** -40°C to +125°C  

### **Descriptions:**
- The TPS79933DDCR is a low-noise, low-dropout linear regulator designed for battery-powered applications.  
- It provides a stable 3.3V output with high PSRR (Power Supply Rejection Ratio) and low quiescent current.  
- Features thermal shutdown and current limit protection.  

### **Features:**
- **Low Dropout:** 110mV at 200mA load  
- **Low Noise:** 30µVRMS (10Hz to 100kHz)  
- **High PSRR:** 75dB at 1kHz  
- **Enable Pin:** Allows shutdown mode for power savings  
- **Thermal Shutdown & Current Limit Protection**  
- **Stable with Ceramic Capacitors** (1µF or greater)  

This LDO is suitable for portable electronics, IoT devices, and other power-sensitive applications.
