Description and Introduction

LNBP SUPPLY AND CONTROL IC WITH STEP-UP CONVERTER AND I2C INTERFACE The **LNBP21D2-TR** is a **low-dropout (LDO) voltage regulator** manufactured by **STMicroelectronics (ST)**. Below are its key specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** STMicroelectronics (ST)  
- **Type:** Low-Dropout (LDO) Voltage Regulator  
- **Output Voltage:** Adjustable (via external resistors) or fixed versions available  
- **Output Current:** Up to **150 mA**  
- **Dropout Voltage:** Typically **200 mV at 100 mA**  
- **Input Voltage Range:** **2.5 V to 6.0 V**  
- **Quiescent Current:** Typically **50 µA**  
- **Line Regulation:** **0.05 %/V** (typical)  
- **Load Regulation:** **0.3 %** (typical)  
- **Operating Temperature Range:** **-40°C to +125°C**  
- **Package:** **SOT23-5L** (small surface-mount package)  

### **Descriptions:**
- The **LNBP21D2-TR** is a **low-power LDO regulator** designed for battery-powered and portable applications.  
- It provides stable voltage regulation with **low dropout voltage**, making it suitable for systems with tight power budgets.  
- The device includes **overcurrent protection** and **thermal shutdown** for reliability.  

### **Features:**
- **Low quiescent current** (50 µA typical) for extended battery life.  
- **Low dropout voltage** (200 mV at 100 mA) for efficient operation.  
- **Adjustable output voltage** (with external resistors) or fixed voltage options.  
- **Thermal shutdown and current limit protection** for safe operation.  
- **Small SOT23-5L package** for space-constrained designs.  

This information is based on STMicroelectronics' official documentation. For detailed application notes and schematics, refer to the **datasheet**.
