Description and Introduction

S OT-23 Plastic-Encapsulate MOSFETS Here is the factual information about part SE3401 from Ic-phoenix technical data files:

### **Manufacturer Specifications**  
- **Manufacturer:** ON Semiconductor  
- **Category:** Voltage Regulator (LDO - Low Dropout)  
- **Output Voltage:** 3.3V (fixed)  
- **Output Current:** 150mA  
- **Input Voltage Range:** 2.5V to 12V  
- **Dropout Voltage:** 300mV (typical at full load)  
- **Quiescent Current:** 85µA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOT-23-3  

### **Descriptions**  
The SE3401 is a low-dropout (LDO) linear voltage regulator designed for low-power applications. It provides a fixed 3.3V output with a maximum current of 150mA. The device is optimized for battery-powered systems, offering low quiescent current and stable performance across a wide input voltage range.  

### **Features**  
- Fixed 3.3V output voltage  
- Low dropout voltage (300mV typical)  
- Low quiescent current (85µA typical)  
- Thermal shutdown protection  
- Short-circuit protection  
- Stable with low-ESR ceramic capacitors  
- Small SOT-23-3 package for space-constrained designs  

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

Application Scenarios & Design Considerations

S OT-23 Plastic-Encapsulate MOSFETS

Alternative Part Number

  • AO3401 --: P-channel MOSFET in SOT-23 with comparable Vds and current ratings, widely used as a direct substitute for SE3401 in load-switch and power-management circuits.
  • SI2301 --: P-channel MOSFET in SOT-23 with similar voltage and current specifications, a common drop-in replacement for SE3401 in low-voltage switching applications.
  • DMG2301L --: P-channel MOSFET in SOT-23 with matching pinout and comparable Rds(on) and current ratings, suitable as an alternative to SE3401.
