Description and Introduction

Low Input Voltage, Any Cap, 1-A Low-Dropout Linear Regulator with Supervisor The TPS72515DCQ is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (TI). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:  

### **Specifications:**  
- **Output Voltage:** 1.5V (fixed)  
- **Output Current:** 500mA  
- **Dropout Voltage:** 340mV (typical) at 500mA  
- **Input Voltage Range:** 2.7V to 6.5V  
- **Accuracy:** ±2% (over line, load, and temperature)  
- **Quiescent Current:** 85µA (typical)  
- **Package:** 6-Pin SOT-223 (DCQ)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Protection Features:**  
  - Thermal shutdown  
  - Overcurrent protection  
  - Reverse current protection  

### **Descriptions:**  
The TPS72515DCQ is a low-dropout linear regulator designed for applications requiring a stable 1.5V supply with high efficiency and low noise. It is suitable for battery-powered devices, portable electronics, and embedded systems.  

### **Features:**  
- **Low Dropout Voltage:** Ensures efficient operation even with small input-output differentials.  
- **Low Quiescent Current:** Extends battery life in portable applications.  
- **Stable with Low-ESR Capacitors:** Works with ceramic capacitors (≥1µF).  
- **High PSRR (Power Supply Rejection Ratio):** Reduces noise in sensitive applications.  
- **Thermal and Overcurrent Protection:** Enhances reliability under fault conditions.  

This information is sourced from TI's official documentation. For further details, refer to the datasheet.

Application Scenarios & Design Considerations

Low Input Voltage, Any Cap, 1-A Low-Dropout Linear Regulator with Supervisor

Alternative Part Number

  • LP38692SD-1.5 --: 1.5V fixed LDO in a similar SOT-223 style package with comparable current capability, pin-compatible enough for many drop-in designs.
  • MIC29152WT --: Adjustable low-dropout regulator that can be set to 1.5V, offers similar current rating and thermal performance as a functional substitute.
  • LT1963AEQ-1.5 --: 1.5V fixed low-noise LDO with comparable dropout and load capability, suitable when higher performance is acceptable.
