Description and Introduction

50-mA, Cap Free, Low Input Voltage, Low-Dropout Linear Regulator 5-SOT-23 -40 to 125 The TPS72218DBVTG4 is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Output Voltage:** 1.8V (Fixed)  
- **Output Current:** 250mA  
- **Dropout Voltage:** 110mV (typical) at 100mA load  
- **Input Voltage Range:** 2.2V to 6.5V  
- **Quiescent Current:** 75µA (typical)  
- **Package:** SOT-23-5 (DBV)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Features:**  
  - Low dropout voltage  
  - Low quiescent current  
  - Thermal shutdown and current limit protection  
  - Stable with ceramic capacitors (1µF or greater)  
  - Fast transient response  

### **Description:**  
The TPS72218DBVTG4 is a fixed-output LDO regulator designed for low-power applications requiring a stable 1.8V supply. It is optimized for battery-powered systems and portable electronics.  

### **Features:**  
- **Low Dropout:** Ensures efficient operation with minimal headroom.  
- **Low Quiescent Current:** Extends battery life in portable applications.  
- **Stable with Ceramic Capacitors:** Reduces cost and board space.  
- **Protection Features:** Includes thermal shutdown and current limiting for reliability.

Application Scenarios & Design Considerations

50-mA, Cap Free, Low Input Voltage, Low-Dropout Linear Regulator 5-SOT-23 -40 to 125

Alternative Part Number

  • LP2985AIM5-1.8 --: Low-dropout linear regulator with fixed 1.8V output in SOT-23-5, functionally similar to the TPS72218 and widely available as a drop-in style alternative.
  • MIC5219-1.8YM5 --: 1.8V fixed LDO regulator in SOT-23-5 with comparable current capability and low dropout, suitable replacement from a different vendor and series.
  • AP2112K-1.8TRG1 --: 1.8V fixed LDO in SOT-23-5 offering similar electrical performance and pin-compatible footprint for many TPS72218 applications.
