Description and Introduction

Single, Current-Limited, Power-Distribution Switch The TPS2051B is a power distribution switch manufactured by Texas Instruments (TI). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Input Voltage Range:** 2.7V to 5.5V  
- **Continuous Current Limit:** 0.5A (typical)  
- **On-Resistance (RDS(ON)):** 95mΩ (typical at 5V)  
- **Operating Temperature Range:** -40°C to 85°C  
- **Package Options:** SOT-23-5  

### **Descriptions:**  
- The TPS2051B is a single-channel power-distribution switch designed for applications requiring precise current limiting.  
- It provides protection for circuits sensitive to excessive current loads.  
- The device features a controlled rise time to minimize inrush current during turn-on.  

### **Features:**  
- **Current Limiting:** Protects the input supply from excessive current loads.  
- **Thermal Shutdown:** Prevents damage due to overheating.  
- **Fast Overcurrent Response:** Reacts quickly to short-circuit conditions.  
- **Low Standby Current:** Reduces power consumption when disabled.  
- **Controlled Turn-On:** Minimizes inrush current.  
- **Reverse Current Blocking:** Prevents current flow from output to input when disabled.  

This information is sourced from TI's official documentation on the TPS2051B.
