Description and Introduction

24V Internal Switch / 100% Duty Cycle / Step-Down Converters The MAX1837EUT33/T is a low-dropout (LDO) linear regulator manufactured by Maxim Integrated. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Output Voltage:** 3.3V (fixed)  
- **Input Voltage Range:** 2.5V to 5.5V  
- **Output Current:** Up to 300mA  
- **Dropout Voltage:** 120mV (typical) at 100mA load  
- **Quiescent Current:** 40µA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOT23-6  

### **Descriptions:**
- The MAX1837EUT33/T is a low-noise, low-dropout linear regulator designed for battery-powered applications.  
- It provides a stable 3.3V output with minimal power loss, making it suitable for portable devices.  
- Features reverse-current protection and thermal shutdown for enhanced reliability.  

### **Features:**
- **Low Dropout Voltage:** Ensures efficient operation even with small input-output differentials.  
- **Low Quiescent Current:** Extends battery life in portable applications.  
- **Stable with Low-ESR Capacitors:** Works with ceramic capacitors as low as 1µF.  
- **Thermal and Short-Circuit Protection:** Safeguards the device under fault conditions.  
- **Reverse-Current Protection:** Prevents damage from reverse voltage conditions.  
- **Enable Pin (SHDN):** Allows for power-saving shutdown mode.  

This regulator is commonly used in portable electronics, wireless devices, and battery-powered systems.

Application Scenarios & Design Considerations

24V Internal Switch / 100% Duty Cycle / Step-Down Converters

Alternative Part Number

  • TPS54232DR --: Wide-input step-down converter with adjustable output that can be set to 3.3V; different series and manufacturer, good electrical substitute for a 3.3V buck regulator.
  • LMR14030SDDAR --: 3A 40V step-down regulator in SOIC-8, easily configured for 3.3V output; different naming and series, suitable drop-in style alternative.
  • MP2359DJ-LF-Z --: Compact 1.2A step-down converter capable of 3.3V output; different manufacturer and part series, useful when board space is limited.
