Description and Introduction

80mA, 10V, Quiescent Current 3.0?A, LDO Linear Regulator in SC70 or SON2x2 5-SC70 -40 to 125 The TPS71433DCKR is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (TI). Here are its key specifications, descriptions, and features:

### **Specifications:**
- **Output Voltage:** 3.3V (fixed)  
- **Input Voltage Range:** 2.5V to 12V  
- **Dropout Voltage:** 340mV (typical at 150mA load)  
- **Output Current:** 150mA (maximum)  
- **Line Regulation:** 0.05% (typical)  
- **Load Regulation:** 0.3% (typical)  
- **Quiescent Current:** 17µA (typical)  
- **Package Type:** SC-70 (DCK), 5-pin  
- **Operating Temperature Range:** -40°C to +125°C  

### **Descriptions:**
- The TPS71433DCKR is a low-power LDO regulator designed for battery-powered applications.  
- It provides a stable 3.3V output with low noise and high PSRR (Power Supply Rejection Ratio).  
- Features thermal shutdown and current limit protection.  

### **Features:**
- **Low Dropout Voltage:** Ensures efficient operation with small input-output differentials.  
- **Low Quiescent Current:** Ideal for power-sensitive applications.  
- **Thermal Shutdown & Current Limit Protection:** Enhances device reliability.  
- **Stable with Low-ESR Capacitors:** Works with ceramic capacitors (≥1µF).  
- **High PSRR:** Reduces noise in sensitive applications.
