Description and Introduction

Ultra Low-Power 50-mA Low-Dropout (LDO) Linear Regulators The TPS77018DBVRG4 is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Output Voltage:** 1.8V (fixed)  
- **Output Current:** 150mA  
- **Dropout Voltage:** 170mV (typical at 100mA load)  
- **Input Voltage Range:** 2.7V to 10V  
- **Quiescent Current:** 17µA (typical)  
- **Line Regulation:** 0.2% (typical)  
- **Load Regulation:** 0.3% (typical)  
- **Package:** SOT-23-5 (DBV)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Features:**  
  - Low dropout voltage  
  - Low quiescent current  
  - Thermal shutdown and overcurrent protection  
  - Stable with low-ESR ceramic capacitors  

### **Descriptions and Features:**  
The TPS77018DBVRG4 is a fixed-output LDO regulator designed for battery-powered applications requiring a stable 1.8V supply. It offers high accuracy, low noise, and low power consumption, making it suitable for portable electronics. The device includes built-in protection features such as thermal shutdown and current limiting. Its small SOT-23-5 package is ideal for space-constrained designs.

Application Scenarios & Design Considerations

Ultra Low-Power 50-mA Low-Dropout (LDO) Linear Regulators

Alternative Part Number

  • LP2985AIM5-1.8 --: Low-dropout 1.8V linear regulator in SOT-23-5 with similar current capability and pinout, a common drop-in substitute for the TPS770xx family.
  • MIC5219-1.8YM5 --: 1.8V LDO regulator in SOT-23-5 with comparable dropout and output current, offered by a different manufacturer and series for easy distinction.
  • AP2112K-1.8TRG1 --: 1.8V fixed LDO in SOT-23-5 with low quiescent current, suitable as a functional replacement when the original TI part is unavailable.
