- **Load Regulation:** 0.1% (typical)  

### **Descriptions:**  
The **TC1108-33VDB** is a **low-dropout (LDO) voltage regulator** designed to provide a stable **3.3V output** from an input voltage range of **2.7V to 6.0V**. It is capable of delivering up to **500mA** of output current with a low dropout voltage of **300mV** (typical at full load).  

This regulator is optimized for **battery-powered applications**, offering low quiescent current (85µA typical) to extend battery life. It includes built-in **overcurrent and thermal protection** for enhanced reliability.  

### **Features:**  
- **Fixed 3.3V output voltage**  
- **500mA output current capability**  
- **Low dropout voltage (300mV typical at 500mA)**  
- **Low quiescent current (85µA typical)**  
- **Wide input voltage range (2.7V to 6.0V)**  
- **Thermal and overcurrent protection**  
- **Stable with low-ESR ceramic capacitors**  
- **5-Pin SOT-23A (SOT-23-5) package**  
- **Operating temperature range: -40°C to +125°C**  

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

Application Scenarios & Design Considerations

300mA CMOS LDO

Alternative Part Number

  • LP2985AIM5-3.3 --: Low-dropout 3.3V linear regulator in SOT-23-5 with similar current capability and pinout, widely available and cost-effective.
  • AP2112K-3.3TRG1 --: 3.3V LDO regulator in SOT-23-5 with low quiescent current and good availability as a drop-in style replacement.
  • MCP1700T-3302E/TT --: Microchip 3.3V LDO in SOT-23 with very low quiescent current, same vendor family style but different series naming.
