Description and Introduction

Lowest Dropout (LDO) PMOS Voltage Regulator with Integrated Supply Voltage Supervisor The TPS7348QD is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (TI). Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**
- **Output Voltage:** 4.85V (fixed)  
- **Output Current:** 500mA  
- **Dropout Voltage:** 110mV (typical) at 500mA  
- **Input Voltage Range:** 2.7V to 5.5V  
- **Accuracy:** ±2% (over line, load, and temperature)  
- **Quiescent Current:** 85µA (typical)  
- **Power Supply Rejection Ratio (PSRR):** 75dB at 1kHz  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 8-pin SOIC (D)  

### **Descriptions:**
- The TPS7348QD is a high-performance, low-noise LDO regulator designed for applications requiring stable and clean power.  
- It features fast transient response and excellent PSRR, making it suitable for noise-sensitive circuits.  
- Includes built-in thermal shutdown, current limit, and reverse-current protection.  

### **Features:**
- **Low Dropout:** 110mV at 500mA  
- **Low Noise:** 30µVRMS (10Hz to 100kHz)  
- **Stable with Ceramic Capacitors:** Requires only a 1µF output capacitor  
- **Thermal Shutdown & Current Limit Protection**  
- **Reverse Current Protection**  
- **Fast Transient Response**  

This information is strictly factual from the TI datasheet for the TPS7348QD.
