Description and Introduction

CMOS fixed +15V output voltage, adjustable output with 2 resistors step-up switching regulator. 5% output accuracy. The MAX633ACSA is a precision voltage reference manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**  
- **Output Voltage Options:** 2.5V, 4.096V, 5.0V (depending on variant).  
- **Initial Accuracy:** ±0.2% (max).  
- **Temperature Coefficient (Tempco):** 15ppm/°C (max).  
- **Output Current:** Up to 10mA.  
- **Line Regulation:** 0.02%/V (max).  
- **Load Regulation:** 0.05%/mA (max).  
- **Operating Temperature Range:** -40°C to +85°C.  
- **Package:** 8-pin SOIC (MAX633ACSA).  
- **Supply Voltage Range:** VOUT + 2V to 40V.  
- **Long-Term Stability:** 30ppm/1000hrs (typ).  

### **Descriptions:**  
The MAX633ACSA is a series voltage reference with low noise, high precision, and excellent temperature stability. It is designed for applications requiring stable voltage references, such as data converters, precision instrumentation, and power supplies.  

### **Features:**  
- **Low Noise:** 5µVp-p (0.1Hz to 10Hz).  
- **Low Dropout Voltage:** 2V (max).  
- **No External Capacitor Required** (stable without compensation).  
- **Wide Supply Voltage Range:** Up to 40V.  
- **Low Quiescent Current:** 400µA (typ).  
- **Short-Circuit Protected.**  

The MAX633ACSA is part of the MAX633 family, which includes variants with different output voltages and package options.  

(Note: Specifications may vary slightly depending on the exact model suffix and datasheet revision.)
