Description and Introduction

Low-Dropout, Low-IQ, 1A Linear Regulator The MAX1793EUE33 is a low-dropout (LDO) linear regulator manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**
- **Output Voltage:** 3.3V (fixed)  
- **Input Voltage Range:** 2.5V to 5.5V  
- **Maximum Output Current:** 500mA  
- **Dropout Voltage:** 120mV (typical at 300mA load)  
- **Quiescent Current:** 85µA (typical)  
- **Shutdown Current:** <1µA  
- **Output Accuracy:** ±2% over line, load, and temperature  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-pin TSSOP (UE)  

### **Descriptions:**
- The MAX1793EUE33 is a high-performance LDO regulator designed for applications requiring a stable 3.3V supply with low dropout and low quiescent current.  
- It includes features like thermal shutdown, current limit protection, and reverse-battery protection.  
- Suitable for battery-powered devices, portable electronics, and noise-sensitive applications.  

### **Features:**
- **Low Dropout Voltage:** Ensures efficient operation even with small input-output differentials.  
- **Low Quiescent Current:** Extends battery life in portable applications.  
- **Thermal and Current-Limit Protection:** Safeguards the device and load.  
- **Reverse-Battery Protection:** Prevents damage from incorrect battery connections.  
- **Stable with Low-ESR Capacitors:** Works with ceramic capacitors (≥1µF).  
- **Enable Input (ON/OFF):** Allows power management control.  

This information is strictly based on the manufacturer's datasheet and technical documentation.

Application Scenarios & Design Considerations

Low-Dropout, Low-IQ, 1A Linear Regulator

Alternative Part Number

  • LP2985AIM5-3.3 --: Low-dropout 3.3V linear regulator in SOT-23-5 with similar current capability and pin-compatible function, widely available and cost-effective.
  • MIC5205-3.3YM5 --: 3.3V LDO regulator in SOT-23-5 offering comparable dropout and output current, suitable drop-in replacement for many MAX1793 applications.
  • TLV70233PDBVR --: 3.3V low-dropout regulator in SOT-23-5 with low quiescent current and stable performance, a good functional substitute for the MAX1793EUE33.
