Description and Introduction

Low-Dropout (LDO) Voltage Regulator The TPS71025D is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:  

### **Specifications:**  
- **Output Voltage:** 2.5V (fixed)  
- **Input Voltage Range:** 2.7V to 10V  
- **Dropout Voltage:** 340mV (typical) at 150mA load  
- **Output Current:** 150mA (maximum)  
- **Line Regulation:** 0.2% (typical)  
- **Load Regulation:** 0.4% (typical)  
- **Quiescent Current:** 85µA (typical)  
- **Package Type:** SOIC-8  
- **Operating Temperature Range:** -40°C to +125°C  

### **Descriptions:**  
- The TPS71025D is a low-dropout linear regulator designed for battery-powered applications.  
- It provides a stable 2.5V output with low noise and high PSRR (Power Supply Rejection Ratio).  
- Includes built-in thermal shutdown and current-limit protection.  

### **Features:**  
- **Low Dropout Voltage:** Ensures efficient operation even with small input-output differentials.  
- **Low Quiescent Current:** Extends battery life in portable applications.  
- **Thermal Shutdown Protection:** Prevents damage from overheating.  
- **Current-Limit Protection:** Safeguards against excessive load conditions.  
- **Stable with Low-ESR Capacitors:** Works with ceramic or tantalum output capacitors.  

This information is sourced from Texas Instruments' official documentation.

Application Scenarios & Design Considerations

Low-Dropout (LDO) Voltage Regulator

Alternative Part Number

  • LP2951ACM --: Adjustable low-dropout regulator in SOIC-8 that can be set to 2.5V output, widely used as a substitute for fixed 2.5V LDOs with similar current capability.
  • MIC5205-2.5YM5 --: Fixed 2.5V low-dropout regulator in SOT-23-5 with low quiescent current, suitable replacement where board space is limited and load current is modest.
  • LM2936Z-2.5 --: Fixed 2.5V LDO regulator in TO-92 with very low quiescent current, good drop-in style alternative for low-power 2.5V regulation applications.
