Description and Introduction

Cap-Free, NMOS, 400mA Low Dropout Regulator with Reverse Current Protection The TPS73630DCQR is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Specifications:**  
- **Output Voltage:** 3.0V (fixed)  
- **Output Current:** 400mA  
- **Dropout Voltage:** 110mV (typical) at 400mA  
- **Input Voltage Range:** 2.2V to 5.5V  
- **Quiescent Current:** 30µA (typical)  
- **PSRR (Power Supply Rejection Ratio):** 70dB at 1kHz  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 6-pin SOT-223 (DCQ)  

### **Descriptions:**  
- The TPS73630DCQR is a low-noise, low-dropout linear regulator designed for battery-powered and noise-sensitive applications.  
- It provides high PSRR and low quiescent current, making it suitable for portable devices.  
- Includes built-in protection features such as thermal shutdown and current limiting.  

### **Features:**  
- **Low Dropout:** 110mV at full load (400mA)  
- **Low Noise:** 30µVRMS (10Hz to 100kHz)  
- **High PSRR:** 70dB at 1kHz  
- **Low IQ:** 30µA (typical)  
- **Thermal Shutdown & Current Limit Protection**  
- **Stable with Ceramic Capacitors** (1µF minimum)
