Description and Introduction

5V/3.3V or Adjustable, Low-Dropout, Low-I The MAX603 is a low-dropout (LDO) linear voltage regulator manufactured by **Maxim Integrated** (now part of Analog Devices). Below are its key specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**
- **Input Voltage Range:** Up to **11.5V** (MAX603) or **16V** (MAX603A).  
- **Output Voltage Options:** Fixed (e.g., **3.3V, 5V**) or adjustable (**1.25V to 11V**).  
- **Output Current:** Up to **500mA**.  
- **Dropout Voltage:** Typically **300mV at 500mA** (low dropout).  
- **Line Regulation:** **0.02%/V** (typical).  
- **Load Regulation:** **0.04%/mA** (typical).  
- **Quiescent Current:** **85µA** (typical).  
- **Operating Temperature Range:** **-40°C to +85°C**.  
- **Package Options:** **TO-220, SO-8, DIP-8**.  

### **Descriptions:**
- The MAX603 is a precision LDO regulator designed for stable voltage regulation with minimal power dissipation.  
- It includes **overcurrent protection** and **thermal shutdown** for safety.  
- Suitable for battery-powered and noise-sensitive applications due to low quiescent current and low output noise.  

### **Features:**
- **Low Dropout Voltage** (300mV at 500mA).  
- **Low Quiescent Current** (85µA).  
- **Adjustable or Fixed Output Voltage** options.  
- **Overcurrent and Thermal Protection**.  
- **Wide Input Voltage Range** (up to 16V for MAX603A).  
- **Stable with Low-ESR Capacitors** (≥1µF).
