### **Descriptions:**  
The TC1055 is a low-dropout (LDO) voltage regulator designed for battery-powered applications. It provides a fixed 3.0V output with high efficiency and low quiescent current, making it suitable for portable and power-sensitive devices.  

### **Features:**  
- **Low Dropout Voltage** (180mV typical at 100mA)  
- **Low Quiescent Current** (50µA typical)  
- **Low Shutdown Current** (<1µA)  
- **Thermal and Overcurrent Protection**  
- **Stable with Low-ESR Capacitors** (≥1µF)  
- **SOT-23-5 Package for Space-Constrained Applications**  
- **Fixed Output Voltage Options Available**

Application Scenarios & Design Considerations

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

Alternative Part Number

  • LP2985AIM5-3.0 --: Low-dropout 3.0V linear regulator in SOT-23-5 with similar current capability and pinout, widely available and cost-effective.
  • MCP1700T-3002E/TT --: Same manufacturer 3.0V LDO in SOT-23 with low quiescent current, easy drop-in for many TC1055 designs.
  • AP2112K-3.0TRG1 --: 3.0V CMOS LDO in SOT-23-5 with low dropout and good stability, suitable functional replacement.
