Description and Introduction

Low-Dropout, 120mA Linear Regulators The MAX8873TEUK-T is a low-dropout (LDO) linear regulator manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 2.5V to 6.5V  
- **Output Voltage Options:** Adjustable (1.25V to 5.5V) or Fixed (1.8V, 2.5V, 2.8V, 3.0V, 3.3V, 5.0V)  
- **Output Current:** Up to 500mA  
- **Dropout Voltage:** 120mV (typical) at 300mA  
- **Quiescent Current:** 85µA (typical)  
- **Shutdown Current:** <1µA  
- **Line Regulation:** 0.02%/V (typical)  
- **Load Regulation:** 0.04%/mA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOT23-5  

### **Descriptions:**  
The MAX8873TEUK-T is a high-performance, low-dropout linear regulator designed for battery-powered applications. It provides stable output voltage with low noise and high efficiency. The device includes thermal shutdown and current-limit protection for enhanced reliability.  

### **Features:**  
- **Low Dropout Voltage:** Enables operation with minimal headroom.  
- **Low Quiescent Current:** Extends battery life in portable devices.  
- **Thermal and Short-Circuit Protection:** Safeguards the regulator and load.  
- **Stable with Ceramic Capacitors:** No need for large output capacitors.  
- **Adjustable or Fixed Output Voltage:** Offers design flexibility.  
- **Fast Transient Response:** Maintains stable output under load changes.  

The MAX8873TEUK-T is commonly used in portable electronics, wireless devices, and embedded systems requiring efficient power management.
