Description and Introduction

ORing MOSFET Controllers with Fastest Fault Isolation for Redundant Power Supplies The MAX8585EUA is a low-dropout (LDO) linear regulator manufactured by Maxim Integrated (now part of Analog Devices). Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**  
- **Input Voltage Range:** 2.5V to 5.5V  
- **Output Voltage Range:** Adjustable (1.25V to 5V) or fixed versions available  
- **Output Current:** Up to 300mA  
- **Dropout Voltage:** 120mV (typical) at 100mA load  
- **Quiescent Current:** 40µA (typical)  
- **Load Regulation:** ±0.05%/mA (typical)  
- **Line Regulation:** 0.05%/V (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin µMAX (MSOP)  

### **Descriptions:**  
The MAX8585EUA is a low-noise, low-dropout linear regulator designed for battery-powered applications. It provides stable output voltage with minimal power loss, making it suitable for portable devices. The adjustable version allows flexibility in setting the output voltage via an external resistor divider.  

### **Features:**  
- **Low Dropout Voltage:** Ensures efficient operation even with small input-output differentials.  
- **Low Quiescent Current:** Extends battery life in portable applications.  
- **Low Noise:** Optimized for noise-sensitive circuits like RF and analog systems.  
- **Thermal and Short-Circuit Protection:** Enhances reliability under fault conditions.  
- **Stable with Low-ESR Capacitors:** Works with ceramic capacitors (≥1µF).  
- **Enable Pin (EN):** Allows shutdown mode, reducing current consumption to <1µA.
