Description and Introduction

3-A, Fast-Transient Response, 1.5-V LDO Voltage Regulator The TPS75815KTT is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (TI). Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Output Voltage:** 1.5V (fixed)  
- **Output Current:** 5A (maximum)  
- **Dropout Voltage:** 300mV (typical at 5A)  
- **Input Voltage Range:** 2.2V to 6V  
- **Line Regulation:** 0.02% (typical)  
- **Load Regulation:** 0.1% (typical)  
- **Accuracy:** ±1% (over line, load, and temperature)  
- **Operating Junction Temperature Range:** -40°C to +125°C  
- **Package:** TO-263-7 (KTT)  

### **Descriptions:**  
The TPS75815KTT is a high-performance LDO regulator designed for applications requiring high current and low dropout voltage. It provides stable power with excellent transient response and thermal performance.  

### **Features:**  
- **High Current Capability:** Supports up to 5A output current.  
- **Low Dropout Voltage:** 300mV typical at full load.  
- **Fast Transient Response:** Optimized for dynamic load changes.  
- **Thermal Protection:** Includes over-temperature shutdown.  
- **Current Limit Protection:** Prevents damage during overload conditions.  
- **Stable with Low-ESR Capacitors:** Works with ceramic or tantalum output capacitors.  
- **Enable Pin:** Allows for power-saving mode when disabled.

Application Scenarios & Design Considerations

3-A, Fast-Transient Response, 1.5-V LDO Voltage Regulator

Alternative Part Number

  • LP3856ET-1.5 --: 1.5V fixed low-dropout linear regulator in TO-220, similar current capability and pin function, easy drop-in for many TPS75815KTT applications.
  • LT1963AET-1.5 --: 1.5V fixed low-noise LDO with comparable dropout and load current, well-proven alternative when TI part is unavailable.
  • MIC29152WT --: Adjustable low-dropout regulator that can be set to 1.5V, high current capability and TO-220 package make it a practical substitute.
