Description and Introduction

5V, Step-Down, Current-Mode PWM DC-DC Converters The MAX738ACPA is a voltage regulator manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX738ACPA  
- **Package:** 8-pin PDIP (Plastic Dual In-line Package)  
- **Input Voltage Range:** +5V to +15V  
- **Output Voltage:** +5V (fixed)  
- **Output Current:** 750mA (max)  
- **Dropout Voltage:** 1V (typical) at 500mA  
- **Quiescent Current:** 1.6mA (typical)  
- **Operating Temperature Range:** 0°C to +70°C  
- **Line Regulation:** 0.02%/V (typical)  
- **Load Regulation:** 0.1% (typical)  
- **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 +5V to +15V. It is suitable for applications requiring a regulated +5V supply with minimal power dissipation.  

### **Features:**  
- **Low Dropout Voltage:** Ensures efficient regulation even when the input voltage is close to the output voltage.  
- **High Output Current:** Supports up to 750mA of continuous output current.  
- **Low Quiescent Current:** Reduces power consumption in standby mode.  
- **Thermal and Overcurrent Protection:** Safeguards the regulator from damage due to excessive current or temperature.  
- **No External Components Required:** Only input and output capacitors are needed for stability.  
- **Fixed +5V Output:** Eliminates the need for external resistors to set the output voltage.  

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

Application Scenarios & Design Considerations

5V, Step-Down, Current-Mode PWM DC-DC Converters

Alternative Part Number

  • LT1073CN8 --: Pin-compatible step-up/inverting switching regulator in DIP-8 with similar input voltage range and current capability, widely used as a MAX738 substitute.
  • MC34063ACP --: Classic general-purpose DC-DC switching regulator in DIP-8, low cost and readily available, suitable for designs where exact switching frequency is not critical.
  • LM2575T-ADJ --: Adjustable step-down switching regulator in TO-220 with higher current rating; a practical alternative when board layout can accommodate a different package.
