Description and Introduction

Photo-IC with linear output Here is the factual information about the TPS856 part from the manufacturer TOS:  

### **Specifications:**  
- **Part Number:** TPS856  
- **Manufacturer:** TOS (Toshiba)  
- **Type:** Voltage Regulator (LDO - Low Dropout)  
- **Output Voltage:** Adjustable or Fixed (specific variant dependent)  
- **Output Current:** Up to 500mA (typical)  
- **Input Voltage Range:** 2.5V to 6.0V  
- **Dropout Voltage:** Low dropout (specific value depends on load)  
- **Package Type:** SOT-23-5 (or other variants)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Quiescent Current:** Low (typically in µA range)  
- **Protection Features:** Overcurrent protection, thermal shutdown  

### **Descriptions:**  
The TPS856 is a low-dropout (LDO) voltage regulator designed for portable and battery-powered applications. It provides stable voltage regulation with minimal power loss, making it suitable for power-sensitive devices.  

### **Features:**  
- Low dropout voltage for efficient operation  
- High output current capability (up to 500mA)  
- Low quiescent current for extended battery life  
- Adjustable or fixed output voltage options  
- Built-in overcurrent and thermal protection  
- Compact SOT-23 package for space-constrained designs  

For exact specifications, refer to the official TOS (Toshiba) datasheet.

Application Scenarios & Design Considerations

Alternative Part Number

  • 2SC1815 --: Widely available general-purpose NPN transistor in the same small-signal class, commonly used as a substitute for older Toshiba 2S-series parts.
  • BC547 --: Standard general-purpose NPN transistor with similar low-power switching characteristics and broad availability.
  • 2N3904 --: Very common general-purpose NPN transistor suitable for low-current switching and amplification, easy to source.
  • TL7705ACP --: Widely available supply-voltage supervisor in DIP-8, functionally similar to the TPS856 supervisory function with easy drop-in evaluation.
  • MC34064P-5 --: Undervoltage sensing circuit in TO-92/DIP package, commonly used as a replacement for simple voltage supervisor ICs like the TPS856.
  • MAX809R --: Low-cost 3-pin microprocessor reset supervisor with active-low reset output, suitable alternative for basic reset/supervisory applications.
