### **Descriptions:**  
The TC2185 is a low-dropout (LDO) voltage regulator from Microchip, designed for low-power applications. It provides a stable 2.8V output with high accuracy and low quiescent current, making it suitable for battery-powered devices.  

### **Features:**  
- Low dropout voltage (300mV typical at 500mA)  
- Low quiescent current (85µA typical)  
- Stable with low-ESR ceramic capacitors  
- Thermal shutdown and current limit protection  
- Fast transient response  
- Small SOT-23-5 package for space-constrained designs  

This information is based on Microchip's official datasheet for the TC2185 series.

Application Scenarios & Design Considerations

50 mA, 100 mA, 150 mA CMOS LDOs with Shutdown and Reference Bypass

Alternative Part Number

  • LP2985AIM5-2.8 --: Low-dropout 2.8V linear regulator in SOT-23-5 with similar 150mA output and low noise, a common pin-compatible substitute for the TC2185.
  • MIC5205-2.8YM5 --: Same manufacturer's 2.8V LDO in SOT-23-5 with comparable dropout and current rating, offering an easy drop-in option from the same vendor.
  • AP2112K-2.8TRG1 --: 2.8V CMOS LDO in SOT-23-5 with 600mA capability and low quiescent current, a widely available alternative for the TC2185 regulator.
