Description and Introduction

5V, Step-Down, Current-Mode PWM DC-DC Converters The MAX738ACPA+ is a voltage regulator IC manufactured by Maxim Integrated (now part of Analog Devices). Below are the factual specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX738ACPA+  
- **Type:** Linear Voltage Regulator  
- **Output Voltage:** +5V (fixed)  
- **Output Current:** 750mA (max)  
- **Input Voltage Range:** 5.2V to 11V  
- **Dropout Voltage:** 500mV (typical at 750mA)  
- **Line Regulation:** 0.02%/V (typical)  
- **Load Regulation:** 0.05% (typical)  
- **Quiescent Current:** 1.6mA (typical)  
- **Package:** 8-pin PDIP (Plastic Dual In-line Package)  
- **Operating Temperature Range:** 0°C to +70°C  
- **Protection Features:** Overcurrent and thermal shutdown  

### **Descriptions:**
The MAX738ACPA+ is a low-dropout (LDO) linear voltage regulator designed to provide a stable +5V output from an input voltage ranging from 5.2V to 11V. It is suitable for applications requiring a regulated 5V supply with moderate current demands (up to 750mA). The device includes built-in protection against overcurrent and excessive temperature.  

### **Features:**
- **Low Dropout Voltage:** Ensures efficient regulation even when input voltage is close to the output.  
- **Low Quiescent Current:** Reduces power consumption in standby modes.  
- **Thermal Shutdown Protection:** Prevents damage due to overheating.  
- **Current Limiting:** Protects the regulator and load from excessive current.  
- **Stable with Low-ESR Capacitors:** Works reliably with ceramic or tantalum output capacitors.  
- **Fixed Output Voltage:** Eliminates the need for external feedback resistors.  

This information is based on the manufacturer's datasheet and technical documentation. For detailed application notes, refer to Maxim Integrated's official resources.
