Description and Introduction

Low-Dropout, 300mA Linear Regulators in SOT23 The MAX8887EZK15+T is a low-dropout (LDO) linear regulator manufactured by **Maxim Integrated** (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Output Voltage:** 1.5V (fixed)  
- **Output Current:** 150mA  
- **Dropout Voltage:** 100mV (typical at 100mA load)  
- **Input Voltage Range:** 2.5V to 5.5V  
- **Quiescent Current:** 30µA (typical)  
- **Accuracy:** ±2% (over line, load, and temperature)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 5-Pin SOT23  

### **Descriptions:**
- The MAX8887 is a **low-noise, low-dropout linear regulator** designed for battery-powered applications.  
- It provides a **stable 1.5V output** with high efficiency and low quiescent current.  
- Includes **thermal shutdown and current-limit protection** for reliability.  

### **Features:**
- **Ultra-Low Dropout Voltage:** Ensures efficient operation even with small input-output differentials.  
- **Low Quiescent Current:** Extends battery life in portable applications.  
- **Stable with Ceramic Capacitors:** Requires only a 1µF output capacitor.  
- **Thermal and Short-Circuit Protection:** Safeguards the device under fault conditions.  
- **Space-Saving SOT23 Package:** Ideal for compact designs.  

This regulator is commonly used in **portable electronics, wireless devices, and battery-powered systems**.

Application Scenarios & Design Considerations

Low-Dropout, 300mA Linear Regulators in SOT23

Alternative Part Number

  • TPS7A2015PDBVR --: Low-noise 1.5V LDO in SOT-23-5 with similar current capability and pinout, widely available and cost-effective.
  • LP5907MFX-1.5/NOPB --: 1.5V ultra-low-noise LDO in SOT-23-5, good drop-in functional match for noise-sensitive loads.
  • AP2112K-1.5TRG1 --: 1.5V fixed LDO in SOT-23-5 with comparable dropout and current rating, suitable lower-cost alternative.
