Description and Introduction

Very Low Dropout (LDO) 1.5 Volt Output 3A LDO With Power Good Output The TPS75715KTTT is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Output Voltage:** 1.5V (Fixed)  
- **Output Current:** 1.5A (Maximum)  
- **Dropout Voltage:** 340mV (Typical) at 1.5A  
- **Input Voltage Range:** 2.2V to 6V  
- **Line Regulation:** 0.02% (Typical)  
- **Load Regulation:** 0.1% (Typical)  
- **Quiescent Current:** 1.3mA (Typical)  
- **Operating Junction Temperature:** -40°C to +125°C  
- **Package:** 5-Pin TO-263 (KTTT)  

### **Descriptions:**
- The TPS75715KTTT is a high-performance LDO regulator designed for applications requiring a stable 1.5V supply.  
- It features low dropout voltage, making it suitable for battery-powered systems.  
- The device includes thermal shutdown and current-limit protection for enhanced reliability.  

### **Features:**
- **High Accuracy:** ±1% output voltage tolerance.  
- **Fast Transient Response:** Optimized for dynamic load conditions.  
- **Thermal Protection:** Shuts down when overheated.  
- **Current Limit Protection:** Prevents damage from excessive current.  
- **Stable with Low-ESR Capacitors:** Works with ceramic capacitors (≥10µF).  
- **Low Noise:** Suitable for noise-sensitive applications.  

This information is based on TI's official datasheet for the TPS75715KTTT.

Application Scenarios & Design Considerations

Very Low Dropout (LDO) 1.5 Volt Output 3A LDO With Power Good Output

Alternative Part Number

  • LT1963AET --: Low-dropout linear regulator with similar 1.5A current capability and adjustable/fixed output options, widely used as a TI LDO alternative.
  • MIC29151-1.5WT --: 1.5A low-dropout regulator in TO-220 package with fixed 1.5V output, functionally comparable to the TPS75715.
  • LM1085IT-1.5 --: 3A low-dropout positive regulator with fixed 1.5V output, same manufacturer family but different series, suitable for higher current margin.
  • LT1963AEQ-1.5 --: Low-dropout 1.5V linear regulator with comparable current capability and thermal performance, from a different series and manufacturer.
  • MIC29152WT --: Adjustable low-dropout regulator that can be set to 1.5V, offering similar dropout and load current in a different package family.
