Description and Introduction

Precision Micropower Shunt Voltage Reference 3-SOT-23 -40 to 85 The TL4051B12IDBZT is a precision voltage reference manufactured by Texas Instruments (TI). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Output Voltage:** 1.225V (Fixed)  
- **Initial Accuracy:** ±0.1% (A Grade), ±0.2% (B Grade)  
- **Temperature Coefficient (Max):** 50 ppm/°C (B Grade)  
- **Operating Current:** 45 µA (Typical)  
- **Output Current:** Up to 15 mA  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOT-23-3 (DBZ)  

### **Descriptions:**  
- The TL4051 is a low-power, precision shunt voltage reference.  
- It provides a stable output voltage with low noise and excellent temperature stability.  
- Suitable for battery-powered and portable applications due to its low quiescent current.  

### **Features:**  
- **Low Dropout Operation:** Works with input voltages as low as 1.24V.  
- **Low Output Noise:** 35 µVpp (Typical)  
- **Wide Operating Current Range:** 60 µA to 15 mA  
- **Stable with Capacitive Loads:** No external capacitor required for stability.  
- **AEC-Q100 Qualified (Available Options)**
