Description and Introduction

350mA, 16.5V Input, Low-Dropout Linear Regulators The MAX1658ESA+T is a step-down DC-DC converter manufactured by Maxim Integrated. Below are the factual details from Ic-phoenix technical data files:

### **Manufacturer:**  
Maxim Integrated  

### **Specifications:**  
- **Input Voltage Range:** 4V to 30V  
- **Output Voltage Range:** Adjustable from 1.25V to 16V  
- **Output Current:** Up to 2A  
- **Switching Frequency:** 300kHz  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-SOIC  

### **Descriptions:**  
The MAX1658ESA+T is a high-efficiency, step-down DC-DC converter designed for applications requiring a regulated output voltage from a higher input voltage. It integrates a power MOSFET switch and provides a compact, efficient solution for power conversion.  

### **Features:**  
- Adjustable output voltage  
- Internal power MOSFET switch  
- Current-mode control for improved transient response  
- Low-dropout operation (100% duty cycle)  
- Overcurrent and thermal protection  
- Soft-start capability  
- Low shutdown current (<10µA)  

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

Application Scenarios & Design Considerations

350mA, 16.5V Input, Low-Dropout Linear Regulators

Alternative Part Number

  • LT1763CS8-3.3#PBF --: Low-dropout linear regulator in an SO-8 package with comparable current capability and low noise, a common drop-in style alternative to the MAX1658 family.
  • TPS7A4901DGNR --: Low-noise, high-PSRR LDO regulator offering similar output current and voltage range, suitable replacement when layout and package constraints allow.
  • LP2985AIM5-3.3/NOPB --: Widely available low-dropout regulator with similar electrical characteristics; smaller SOT-23 package makes it a practical alternative for space-constrained designs.
  • LT1963AEST-3.3#PBF --: Low-dropout regulator with similar output current and voltage range, good noise performance, and a mature, well-stocked alternative for MAX1658 applications.
