### **Description:**  
The TC2055-3.3VCTTR is a low-dropout (LDO) voltage regulator from Microchip, designed to provide a stable 3.3V output with minimal power loss. It is suitable for battery-powered and low-power applications due to its low quiescent current and dropout voltage.  

### **Features:**  
- **Low Dropout Voltage:** Ensures efficient operation even with small input-output differentials.  
- **Low Quiescent Current:** Ideal for battery-operated devices.  
- **Protection Features:** Includes thermal shutdown and short-circuit protection for reliability.  
- **Wide Input Voltage Range:** Compatible with various power sources.  
- **Stable with Ceramic Capacitors:** No need for bulky capacitors, saving board space.  

This LDO is commonly used in portable electronics, IoT devices, and other applications requiring stable voltage regulation.

Application Scenarios & Design Considerations

50 mA, 100 mA, and 150 mA CMOS LDOs with Shutdown and Error Output

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.
  • MCP1700T-3302E/TT --: Same manufacturer family, 3.3V LDO in SOT-23 with low quiescent current, easy drop-in for many TC2055 designs.
  • AP2112K-3.3TRG1 --: 3.3V CMOS LDO in SOT-23-5 with low dropout and stable output, suitable replacement when layout allows.
  • MIC5205-3.3YM5 --: Same manufacturer family of 3.3V LDO regulators in SOT-23-5, good electrical match with familiar supply chain.
