Description and Introduction

150-mA LDO REGULATORS WITH 8-PIN MSOP PACKAGING The TPS77128DGKR is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Output Voltage:** 2.8V (fixed)  
- **Output Current:** 150mA  
- **Dropout Voltage:** 110mV (typical) at 100mA  
- **Input Voltage Range:** 2.7V to 10V  
- **Line Regulation:** 0.02%/V (typical)  
- **Load Regulation:** 0.1% (typical)  
- **Quiescent Current:** 75µA (typical)  
- **Package:** 8-pin VSSOP (DGK)  
- **Operating Temperature Range:** -40°C to +125°C  

### **Descriptions:**  
- The TPS77128DGKR is a low-power LDO regulator designed for battery-powered applications.  
- It provides a stable 2.8V output with high accuracy (±2%).  
- Features low dropout voltage and low quiescent current for extended battery life.  
- Includes thermal shutdown and current-limit protection.  

### **Features:**  
- **Low Dropout Voltage:** Ensures efficient operation even with small input-output differentials.  
- **Low Quiescent Current:** Ideal for power-sensitive applications.  
- **Thermal Shutdown Protection:** Prevents damage from overheating.  
- **Current-Limit Protection:** Safeguards against excessive load currents.  
- **Stable with Low-ESR Capacitors:** Works with ceramic capacitors (≥1µF).  
- **Fast Transient Response:** Suitable for dynamic load conditions.  

This information is based on TI's official datasheet for the TPS77128DGKR.

Application Scenarios & Design Considerations

150-mA LDO REGULATORS WITH 8-PIN MSOP PACKAGING

Alternative Part Number

  • LP2985AIM5-2.8 --: Low-dropout linear regulator with 2.8V fixed output in SOT-23-5, similar current capability and pin-compatible function for many applications.
  • MIC5205-2.8YM5 --: 2.8V fixed LDO regulator in SOT-23-5 with low dropout and low quiescent current, a common cross-reference for TI LDOs.
  • AP2112K-2.8TRG1 --: 2.8V fixed LDO in SOT-23-5 with 600mA capability, widely available and functionally similar to the original regulator.
