Description and Introduction

Low-Dropout / 300mA Linear Regulator in MAX The MAX8860EUA25 is a low-dropout (LDO) linear regulator manufactured by **Maxim Integrated** (now part of Analog Devices). Below are its key specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**  
- **Output Voltage:** 2.5V (fixed)  
- **Output Current:** 150mA  
- **Dropout Voltage:** 120mV (typical at 100mA load)  
- **Input Voltage Range:** 2.5V to 6.5V  
- **Quiescent Current:** 85µA (typical)  
- **Shutdown Current:** <1µA  
- **Line Regulation:** 0.02%/V (typical)  
- **Load Regulation:** 0.05%/mA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin µMAX (UA)  

### **Descriptions:**  
- The MAX8860EUA25 is a **low-noise, low-dropout linear regulator** designed for battery-powered applications.  
- It provides a **fixed 2.5V output** with high accuracy (±1.5% over line, load, and temperature).  
- Includes **thermal shutdown and current-limit protection** for safe operation.  
- Optimized for **low-power portable devices** such as wireless sensors, medical instruments, and handheld electronics.  

### **Features:**  
- **Ultra-Low Dropout Voltage:** 120mV at 100mA load.  
- **Low Quiescent Current:** 85µA (typical) for extended battery life.  
- **Low Noise Output:** Minimizes interference in sensitive circuits.  
- **Shutdown Mode:** Reduces power consumption to <1µA.  
- **Stable with Small Capacitors:** Works with ceramic capacitors ≥1µF.  
- **Thermal and Current-Limit Protection:** Prevents damage from overheating or overcurrent.  

This information is sourced from the manufacturer's datasheet and technical documentation.

Application Scenarios & Design Considerations

Low-Dropout / 300mA Linear Regulator in MAX

Alternative Part Number

  • LP2985AIM5-2.5 --: Low-dropout linear regulator with fixed 2.5V output in SOT-23-5, similar current capability and pinout, widely available and cost-effective.
  • ADP151AUJZ-2.5 --: Ultra-low-noise 200mA LDO with 2.5V fixed output in TSOT-5, good drop-in functional replacement for noise-sensitive designs.
  • TLV70225PDBVR --: 300mA low-dropout regulator with 2.5V fixed output in SOT-23-5, offers comparable performance with lower quiescent current.
  • MIC5205-2.5YM5 --: 150 mA low-dropout regulator in SOT-23-5 with 2.5 V fixed output and low quiescent current, a common drop-in style alternative.
