Description and Introduction

Micropower Very Low Dropout (LDO) PMOS Voltage Regulator The TPS7248QD is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Output Voltage:** 4.8V (fixed)  
- **Output Current:** 500mA  
- **Dropout Voltage:** 300mV (typical) at 500mA  
- **Input Voltage Range:** 2.7V to 10V  
- **Line Regulation:** 0.04% (typical)  
- **Load Regulation:** 0.2% (typical)  
- **Quiescent Current:** 1mA (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOIC-8 (D)  

### **Descriptions:**
- The TPS7248QD is a high-performance LDO regulator designed for applications requiring stable and efficient voltage regulation.  
- It features low dropout voltage, making it suitable for battery-powered devices.  
- Includes built-in protection features such as thermal shutdown and current limiting.  

### **Features:**
- **Low Dropout Voltage:** Ensures efficient operation even with small input-output differentials.  
- **Thermal Shutdown Protection:** Prevents damage from excessive heat.  
- **Current Limit Protection:** Safeguards against overcurrent conditions.  
- **Stable with Low-ESR Capacitors:** Works reliably with ceramic or tantalum output capacitors.  
- **Fast Transient Response:** Maintains stable output under varying load conditions.  

This information is based solely on the manufacturer's datasheet for the TPS7248QD.

Application Scenarios & Design Considerations

Micropower Very Low Dropout (LDO) PMOS Voltage Regulator

Alternative Part Number

  • LP2985AIM5-5.0 --: Low-dropout linear regulator in a different series with similar 5V fixed output and low quiescent current, suitable for similar low-power applications.
  • MIC5205-5.0YM5 --: 5V fixed LDO regulator from a different vendor and series, offering comparable dropout and load capability as a drop-in style alternative.
  • LT1761ES5-5 --: Low-noise 5V LDO in a different product family with similar current rating and package style, usable where low dropout and stability are required.
  • TPS7A4901DGNR --: High-voltage low-dropout linear regulator in the same TI LDO family, offering similar regulation performance and a wide input range suitable for replacing the TPS7248QD in many designs.
  • LM317LIDR --: Classic adjustable linear regulator with a different series name, widely available and cost-effective, providing a simple drop-in style solution when adjustable output and moderate current are acceptable.
  • LT1963AEST-3.3#PBF --: Low-noise, fast-transient LDO from a different manufacturer and series, suitable as a higher-performance alternative when fixed 3.3V output and improved noise/PSRR are required.
