Description and Introduction

5V/3.3V or Adjustable, Low-Dropout, Low IQ, 500mA Linear Regulators The MAX603ESA is a low-dropout linear voltage regulator manufactured by Maxim Integrated. Below are its specifications, descriptions, and features:

### **Specifications:**  
- **Output Voltage Options:** 3.0V, 3.3V, 5.0V (fixed) or adjustable (1.25V to 11.5V).  
- **Output Current:** Up to 500mA.  
- **Dropout Voltage:** 120mV (typical) at 100mA load.  
- **Input Voltage Range:** Up to 11.5V.  
- **Line Regulation:** 0.02%/V (typical).  
- **Load Regulation:** 0.04%/mA (typical).  
- **Quiescent Current:** 75µA (typical).  
- **Package:** 8-pin SOIC (ESA).  
- **Operating Temperature Range:** -40°C to +85°C.  

### **Descriptions:**  
The MAX603ESA is a precision, low-dropout linear regulator designed for battery-powered and low-voltage applications. It provides stable output voltage with minimal power loss and includes features like thermal shutdown and current limiting for protection.  

### **Features:**  
- Low dropout voltage (120mV at 100mA).  
- Low quiescent current (75µA).  
- Thermal shutdown and current-limit protection.  
- Stable with low-ESR capacitors.  
- Adjustable or fixed output voltage options.  
- Low noise output.  

This information is based solely on the manufacturer's datasheet.
