Description and Introduction

Low-Voltage Reference The MAX8069ESA+ 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 data:

### **Specifications:**  
- **Input Voltage Range:** 2.5V to 6.5V  
- **Output Voltage Options:** Fixed (1.2V, 1.5V, 1.8V, 2.5V, 2.8V, 3.0V, 3.3V, 5.0V) or Adjustable (1.25V to 5.5V)  
- **Output Current:** 500mA  
- **Dropout Voltage:** 120mV (typical) at 100mA load  
- **Accuracy:** ±1.5% (over line, load, and temperature)  
- **Quiescent Current:** 85µA (typical)  
- **Shutdown Current:** <1µA  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin SOIC (ESA+)  

### **Descriptions:**  
- The MAX8069ESA+ is a low-noise, low-dropout linear regulator designed for battery-powered and noise-sensitive applications.  
- It provides stable output voltage with low quiescent current, making it suitable for portable devices.  
- Includes thermal shutdown and current-limit protection.  

### **Features:**  
- **Low Dropout Voltage:** 120mV (typical) at 100mA.  
- **Low Noise:** Optimized for RF and precision analog circuits.  
- **Low Quiescent Current:** 85µA (typical).  
- **Enable/Shutdown Control:** Logic-controlled shutdown reduces power consumption.  
- **Thermal and Current-Limit Protection:** Prevents damage from overheating or overload.  
- **Stable with Low-ESR Ceramic Capacitors:** Reduces external component count.  

This information is sourced from the manufacturer's datasheet. For detailed application notes, refer to MAXIM (now Analog Devices) documentation.

Application Scenarios & Design Considerations

Low-Voltage Reference

Alternative Part Number

  • LM4040DIM3-2.5 --: Precision 2.5V shunt voltage reference in SOT-23, functionally similar to the MAX8069 2.5V reference and widely available.
  • TL431ACDBZR --: Adjustable shunt reference that can be set to 2.5V, a common and cost-effective substitute for 2.5V shunt references.
  • ZR40402F25TA --: 2.5V precision shunt reference in SOT-23, direct functional replacement for 2.5V shunt reference applications.
  • LM4040DIZ-2.5 --: 2.5V precision shunt voltage reference in a similar package, widely available and pin-compatible in most designs.
  • TL431AILP --: Adjustable shunt reference that can be set to 2.5V, very common and cost-effective substitute for many reference applications.
  • REF3025AIDBZT --: 2.5V series voltage reference with low drift, suitable when a series-mode reference is acceptable instead of a shunt type.
