Description and Introduction

Low-Voltage, 400mA Step-Down DC-DC Converters in SOT23 The MAX1921EUT15+ is a low-dropout (LDO) linear regulator manufactured by **MAXIM** (now part of Analog Devices).  

### **Specifications:**  
- **Output Voltage:** 1.5V (fixed)  
- **Input Voltage Range:** 2.5V to 5.5V  
- **Maximum Output Current:** 150mA  
- **Dropout Voltage:** 120mV (typical at 100mA load)  
- **Quiescent Current:** 40µA (typical)  
- **Load Regulation:** ±0.05% (typical)  
- **Line Regulation:** 0.02%/V (typical)  
- **Output Accuracy:** ±2% over line, load, and temperature  
- **Package:** SOT-23-6  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
The MAX1921EUT15+ 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, making it suitable for portable devices.  

### **Features:**  
- Low dropout voltage (120mV at 100mA)  
- Low quiescent current (40µA typical)  
- Stable with low-ESR ceramic capacitors  
- Thermal shutdown and current-limit protection  
- Tiny SOT-23-6 package for space-constrained designs  
- Low output noise  

This regulator is ideal for applications requiring a stable, low-noise power supply, such as portable electronics, wireless devices, and battery-powered systems.
