Description and Introduction

+72V SOT23/TDFN Simple Swapper Hot-Swap Controllers The MAX5903LBEUT is a power management IC manufactured by Maxim Integrated. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Manufacturer:**  
MAXIM (now part of Analog Devices)  

### **Part Number:**  
MAX5903LBEUT  

### **Description:**  
The MAX5903LBEUT is a simple, low-dropout (LDO) linear regulator designed for power-over-Ethernet (PoE) applications. It provides a regulated output voltage from an input derived from a PoE source.  

### **Key Features:**  
- **Input Voltage Range:** 12V to 57V (compatible with IEEE 802.3af PoE standards)  
- **Output Voltage:** 3.3V (fixed)  
- **Output Current:** Up to 100mA  
- **Low Dropout Voltage:** 300mV (typical)  
- **Thermal Overload Protection:** Yes  
- **Short-Circuit Protection:** Yes  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOT-23-6  

### **Applications:**  
- Power-over-Ethernet (PoE) devices  
- Network cameras (IP cameras)  
- VoIP phones  
- Wireless access points  

### **Additional Notes:**  
- The device includes internal current limiting and thermal shutdown for protection.  
- It is designed for space-constrained applications due to its small SOT-23 package.  

This information is based solely on the manufacturer's datasheet and product specifications.
