Description and Introduction

1.2A, Current-Limited, High-Side P-Channel Switch with Thermal Shutdown The MAX890L is a low-dropout linear regulator (LDO) manufactured by **Maxim Integrated** (now part of Analog Devices). Below are its key specifications, descriptions, and features based on available data:  

### **Specifications:**  
- **Input Voltage Range:** 2.5V to 5.5V  
- **Output Voltage:** Adjustable (1.25V to 5.0V) or fixed (1.8V, 2.5V, 3.0V, 3.3V)  
- **Output Current:** 500mA  
- **Dropout Voltage:** 120mV (typical at 500mA load)  
- **Quiescent Current:** 85µA (typical)  
- **Shutdown Current:** <1µA  
- **Line Regulation:** 0.05%/V (typical)  
- **Load Regulation:** 0.1%/A (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Options:** 5-pin SOT23, 8-pin µMAX  

### **Descriptions:**  
- The MAX890L is a high-performance, low-dropout linear regulator designed for battery-powered and portable applications.  
- It provides stable output voltage with low noise and high PSRR (Power Supply Rejection Ratio).  
- Includes thermal shutdown and current-limit protection.  

### **Features:**  
- **Low Dropout Voltage:** 120mV at 500mA load  
- **Low Quiescent Current:** 85µA (extends battery life)  
- **Adjustable or Fixed Output Voltage Options**  
- **Thermal Shutdown Protection**  
- **Current-Limit Protection**  
- **Stable with Low-ESR Ceramic Capacitors**  
- **Small Package Options (SOT23, µMAX) for Space-Constrained Designs**
