Description and Introduction

50 mA, 24 V, 3.2 uA Supply Current Low-Dropout Linear Regulator The TPS71550DCKRG4 is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Input Voltage Range:** 2.5V to 6.5V  
- **Output Voltage:** 5.0V (fixed)  
- **Output Current:** 150mA  
- **Dropout Voltage:** 300mV (typical) at 150mA  
- **Line Regulation:** 0.04% (typical)  
- **Load Regulation:** 0.2% (typical)  
- **Quiescent Current:** 85µA (typical)  
- **Package:** SC-70 (DCK), 5-Pin  
- **Operating Temperature Range:** -40°C to +125°C  
- **Features:**  
  - Low quiescent current  
  - Thermal shutdown protection  
  - Short-circuit protection  
  - Stable with low-ESR ceramic capacitors  

### **Descriptions and Features:**  
The TPS71550DCKRG4 is a low-power LDO regulator designed for battery-powered applications. It provides a fixed 5V output with high accuracy and low dropout voltage. The device includes thermal shutdown and current-limiting protection for enhanced reliability. Its small SC-70 package makes it suitable for space-constrained designs.

Application Scenarios & Design Considerations

50 mA, 24 V, 3.2 uA Supply Current Low-Dropout Linear Regulator

Alternative Part Number

  • LP2985AIM5-5.0 --: Low-dropout 5.0V linear regulator in SOT-23-5 with similar current capability and pinout, widely available and a common drop-in substitute.
  • MIC5205-5.0YM5 --: 5.0V LDO regulator in SOT-23-5 with comparable dropout and quiescent current, suitable replacement from a different vendor.
  • AP2112K-5.0TRG1 --: 5.0V CMOS LDO in SOT-23-5 offering similar performance and a distinct part series, good for cost-sensitive designs.
