Description and Introduction

Current-Limited, High-Side P-Channel Switches with Thermal Shutdown The MAX892LEUA is a low-dropout (LDO) linear regulator manufactured by Maxim Integrated (now part of Analog Devices). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Input Voltage Range:** 2.5V to 6.5V  
- **Output Voltage Options:** Adjustable (1.25V to 5.5V) or Fixed (1.8V, 2.5V, 2.8V, 3.0V, 3.3V, 5.0V)  
- **Output Current:** Up to 150mA  
- **Dropout Voltage:** 120mV (typical) at 100mA load  
- **Quiescent Current:** 30µA (typical)  
- **Line Regulation:** 0.02%/V (typical)  
- **Load Regulation:** 0.05%/mA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin µMAX (3mm x 3mm)  

### **Descriptions:**  
- The MAX892LEUA is a low-power, low-dropout linear regulator designed for battery-powered applications.  
- It provides stable output voltage with low noise and high PSRR (Power Supply Rejection Ratio).  
- The device includes thermal shutdown and current-limit protection.  

### **Features:**  
- **Low Dropout Voltage:** Ensures efficient operation with minimal headroom.  
- **Low Quiescent Current:** Extends battery life in portable devices.  
- **Adjustable or Fixed Output Voltage:** Offers flexibility in design.  
- **Thermal Shutdown Protection:** Prevents overheating damage.  
- **Current Limit Protection:** Safeguards against excessive load currents.  
- **Small Footprint:** Suitable for space-constrained applications.

Alternative Part Number

  • LTC1151CSW --: Pin-compatible high-side current-sense amplifier with similar supply range and function, from a different series and vendor.
  • INA138NA/3K --: High-side current shunt monitor offering comparable sensing function and accuracy in a small package, different naming and vendor.
  • ZXCT1009FTA --: Low-cost high-side current monitor with similar operating principle and supply range, clearly different series and manufacturer.
  • LTC1921CMS8 --: Pin-compatible high-side current-sense amplifier with similar function and supply range; widely available and often used as a MAX892 replacement.
  • INA195AIDBVR --: Current-shunt monitor with comparable gain and voltage range, available in small packages; good functional substitute for current-sensing applications.
  • AD8210YRZ --: High common-mode current-sense amplifier offering similar performance and robust supply range; suitable alternative when MAX892 is unavailable.
  • LTC1473LCGN --: Pin-compatible P-channel MOSFET driver/current-sense IC in the same function class; widely used as a MAX892 drop-in in power-path circuits.
  • TPS2412PWR --: ORing power controller with similar voltage range and logic-level enable, suitable replacement for load-switching and reverse-current protection.
  • ISL6146BIRZ --: Low-voltage ORing MOSFET controller offering comparable gate drive and current-sense behavior for redundant power supply designs.
