Description and Introduction

500mA Low-Dropout Linear Regulator in レMAX The MAX1792EUA50 is a step-up DC-DC converter manufactured by Maxim Integrated (now part of Analog Devices). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX1792EUA50  
- **Type:** Step-Up DC-DC Converter  
- **Output Voltage:** 5V (fixed)  
- **Input Voltage Range:** 0.8V to 5.5V  
- **Output Current:** Up to 300mA (depending on input voltage)  
- **Switching Frequency:** 500kHz (typical)  
- **Efficiency:** Up to 92%  
- **Package:** 8-pin µMAX® (ultra-small outline)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**
The MAX1792EUA50 is a high-efficiency, step-up DC-DC converter designed for low-input voltage applications. It integrates a power switch, synchronous rectifier, and control circuitry to deliver a regulated 5V output from input voltages as low as 0.8V. The device is optimized for battery-powered systems, portable electronics, and other applications requiring compact power management solutions.

### **Features:**
- **Wide Input Voltage Range:** Operates from 0.8V to 5.5V.  
- **Fixed 5V Output:** No external feedback resistors required.  
- **High Efficiency:** Up to 92% with synchronous rectification.  
- **Low Quiescent Current:** 30µA (typical) in shutdown mode.  
- **Internal Soft-Start:** Reduces inrush current during startup.  
- **Thermal Shutdown Protection:** Prevents damage from overheating.  
- **Small Footprint:** 8-pin µMAX package (3mm x 3mm).  

This information is based on the manufacturer's datasheet and technical documentation. For detailed application notes or additional specifications, refer to the official MAX1792 datasheet.

Application Scenarios & Design Considerations

500mA Low-Dropout Linear Regulator in レMAX

Alternative Part Number

  • LP2985AIM5-5.0 --: Low-dropout linear regulator with fixed 5.0V output in SOT-23-5, similar current capability and pinout, widely available and cost-effective.
  • MIC5205-5.0YM5 --: 5.0V fixed LDO regulator in SOT-23-5 with low dropout and low quiescent current, suitable drop-in replacement for many MAX1792 applications.
  • TLV70250DBVR --: 5.0V fixed-output LDO in SOT-23-5 with low dropout, stable with small ceramic capacitors, and good alternative when supply availability of the original is limited.
