Description and Introduction

200mA Low Quiescent Current, Ultra-Low Noise, High PSRR LDO The TPS79930DDCR is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (TI). Here are its key specifications, descriptions, and features:

### **Specifications:**
- **Output Voltage:** 3.0V (fixed)  
- **Output Current:** 200mA  
- **Dropout Voltage:** 110mV (typical) at 200mA  
- **Input Voltage Range:** 2.5V to 6.5V  
- **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 TPS79930DDCR is a high-performance, low-noise LDO regulator designed for battery-powered applications.  
- It provides stable voltage regulation with low dropout and minimal power consumption.  
- The device includes features like thermal shutdown and current limit protection.  

### **Features:**
- **Low Dropout:** 110mV at 200mA  
- **Low Noise:** 30µVRMS (10Hz to 100kHz)  
- **Low IQ:** 17µA (typical)  
- **Fast Transient Response**  
- **Thermal Shutdown & Overcurrent Protection**  
- **Stable with Low-ESR Ceramic Capacitors (≥1µF)**  

This information is based on TI's official datasheet for the TPS79930DDCR.

Description and Introduction

200mA Low Quiescent Current, Ultra-Low Noise, High PSRR LDO The TPS79930DDCR is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Output Voltage:** 3.0V (fixed)  
- **Output Current:** 200mA  
- **Input Voltage Range:** 2.7V to 6.5V  
- **Dropout Voltage:** 175mV (typical at 200mA load)  
- **Accuracy:** ±2% (over line, load, and temperature)  
- **Quiescent Current:** 17µA (typical)  
- **PSRR (Power Supply Rejection Ratio):** 75dB (at 1kHz)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOT-23-5 (DDC)  

### **Descriptions:**
- The TPS79930DDCR is a high-performance, low-noise LDO regulator designed for battery-powered and noise-sensitive applications.  
- It provides a stable 3.0V output with excellent line and load transient response.  
- The device includes features like thermal shutdown and current limit protection.  

### **Features:**
- **Ultra-Low Noise:** 30µVRMS (10Hz to 100kHz)  
- **Low Dropout:** Enables operation with very small input-to-output differentials.  
- **High PSRR:** Ensures stable output even with noisy input supplies.  
- **Enable Pin:** Allows power-saving shutdown mode when not in use.  
- **Thermal Shutdown & Current Limit Protection:** Protects the device from overheating and overcurrent conditions.  
- **Stable with Ceramic Capacitors:** Requires only a 1µF output capacitor for stability.  

This regulator is commonly used in portable electronics, medical devices, and precision analog circuits.
