Description and Introduction

1A / Current-Limited / High-Side P-Channel Switch with Thermal Shutdown The MAX890LESA is a voltage regulator from Maxim Integrated (now part of Analog Devices). Below are the factual details about the part:

### **Manufacturer:**  
- **MAX** (Maxim Integrated, now part of Analog Devices)  

### **Specifications:**  
- **Type:** Low-Dropout (LDO) Voltage Regulator  
- **Output Voltage:** Fixed or Adjustable (specific variant dependent)  
- **Output Current:** Typically up to 150mA  
- **Dropout Voltage:** Low dropout (exact value depends on load conditions)  
- **Input Voltage Range:** Up to 5.5V (exact range may vary)  
- **Quiescent Current:** Low (typically in the microamp range for efficiency)  
- **Package:** 8-pin SOIC (Small Outline Integrated Circuit)  

### **Descriptions:**  
- The MAX890LESA is a low-dropout linear regulator designed for applications requiring stable voltage with minimal power loss.  
- It is suitable for battery-powered devices, portable electronics, and other low-power systems.  
- Features include thermal shutdown and current limiting for protection.  

### **Features:**  
- **Low Dropout Voltage:** Ensures efficient regulation even with small input-output differentials.  
- **Low Quiescent Current:** Extends battery life in portable applications.  
- **Thermal Shutdown Protection:** Prevents damage from overheating.  
- **Current Limit Protection:** Safeguards against excessive load conditions.  
- **Stable with Low-ESR Capacitors:** Works well with cost-effective ceramic capacitors.

Application Scenarios & Design Considerations

1A / Current-Limited / High-Side P-Channel Switch with Thermal Shutdown

Alternative Part Number

  • TPS2041BDBVR --: Pin-compatible current-limited high-side power switch with similar voltage/current ratings and enable control, widely available and often used as a MAX890L substitute.
  • MIC2026-1YM --: Dual-channel current-limiting power distribution switch with comparable operating range and thermal shutdown, suitable for load-switch applications replacing the MAX890L.
  • AP2553W6-7 --: Single-channel current-limited high-side switch with adjustable current limit and similar package options, a cost-effective functional alternative.
