Description and Introduction

5V/3.3V or Adjustable, Low-Dropout, Low IQ, 500mA Linear Regulators The MAX603CPA is a precision voltage reference manufactured by Maxim Integrated (now part of Analog Devices). Here are its specifications, descriptions, and features:

### **Specifications:**  
- **Output Voltage:** 2.5V, 4.096V, or 5.0V (depending on variant)  
- **Initial Accuracy:** ±0.2% (MAX603A), ±0.4% (MAX603B)  
- **Temperature Coefficient (Tempco):** 15ppm/°C (MAX603A), 25ppm/°C (MAX603B)  
- **Supply Voltage Range:** VOUT + 2V to 12.6V  
- **Output Current:** Up to 10mA  
- **Low Dropout Voltage:** 1mV/mA  
- **Operating Temperature Range:** 0°C to +70°C (Commercial Grade)  
- **Package:** 8-pin PDIP (Plastic Dual In-Line Package)  

### **Descriptions:**  
The MAX603CPA is a low-power, precision voltage reference with high accuracy and low temperature drift. It is designed for applications requiring stable voltage references, such as data converters, power supplies, and instrumentation.  

### **Features:**  
- **Low Noise:** 30µVp-p (0.1Hz to 10Hz)  
- **Low Quiescent Current:** 100µA (typical)  
- **No External Capacitor Required** (stable without one)  
- **Reverse-Battery Protection**  
- **Short-Circuit Protected**  
- **Low Thermal Hysteresis**  

The MAX603CPA is part of Maxim's family of precision voltage references, offering reliable performance for industrial and commercial applications.  

(Note: Always verify datasheet details for exact variant specifications.)
