Description and Introduction

LOW-DROPOUT VOLTAGE REGULATORS The TPS7148QDR is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (TI). Below are the specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:  

### **Specifications:**  
- **Output Voltage:** 4.85V (Fixed)  
- **Output Current:** 250mA  
- **Dropout Voltage:** 340mV (Typical at 250mA)  
- **Input Voltage Range:** 2.7V to 10V  
- **Line Regulation:** 0.02%/V (Typical)  
- **Load Regulation:** 0.1% (Typical)  
- **Quiescent Current:** 85µA (Typical)  
- **Package:** SOIC-8 (D)  
- **Operating Temperature Range:** -40°C to +125°C  
- **PSRR (Power Supply Rejection Ratio):** 70dB at 1kHz  

### **Descriptions:**  
The TPS7148QDR is a low-dropout linear regulator designed for applications requiring a stable and precise 4.85V supply. It features low quiescent current, making it suitable for battery-powered devices. The regulator includes thermal shutdown and current-limiting protection for enhanced reliability.  

### **Features:**  
- **Low Dropout Voltage:** Ensures efficient operation with minimal headroom.  
- **Low Quiescent Current:** Ideal for power-sensitive applications.  
- **Thermal Shutdown & Current Limit Protection:** Protects the device from overheating and overcurrent conditions.  
- **Stable with Low-ESR Capacitors:** Works with ceramic or tantalum output capacitors.  
- **High PSRR:** Provides excellent noise rejection for sensitive circuits.  
- **Fixed Output Voltage:** Eliminates the need for external resistors.  

This information is based solely on TI's official datasheet for the TPS7148QDR.
