Description and Introduction

Low-Input-Voltage, 500mA LDO Regulator with Active-Low RESET in SOT and TDFN The MAX1589ETT250+T is a high-efficiency, step-up DC-DC converter manufactured by **MAXIM**.  

### **Specifications:**  
- **Input Voltage Range:** 0.7V to 5.5V  
- **Output Voltage:** 2.5V (fixed)  
- **Output Current:** Up to 300mA  
- **Switching Frequency:** 1.2MHz  
- **Efficiency:** Up to 94%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 6-pin TDFN (2mm x 2mm)  

### **Descriptions:**  
The MAX1589ETT250+T is designed for low-input-voltage applications, such as single-cell or dual-cell alkaline/NiMH battery-powered devices. It integrates a synchronous rectifier for high efficiency and includes a soft-start feature to limit inrush current.  

### **Features:**  
- **True Shutdown Mode** (Output disconnected from input)  
- **Internal Synchronous Rectifier** (Improves efficiency)  
- **Low Quiescent Current** (25µA typical)  
- **Soft-Start Function** (Reduces inrush current)  
- **Thermal Shutdown Protection**  
- **Small Footprint** (TDFN package)  

This device is suitable for portable electronics, medical devices, and other low-power applications requiring stable voltage conversion.
