Description and Introduction

Fast-Transient-Response 150-mA LDO W/Reset, MSOP-8 Packaging The TPS77150DGKR is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Output Voltage:** 1.5V (fixed)  
- **Output Current:** 150mA  
- **Dropout Voltage:** 110mV (typical) at 100mA  
- **Input Voltage Range:** 2.7V to 10V  
- **Line Regulation:** 0.2% (typical)  
- **Load Regulation:** 0.3% (typical)  
- **Quiescent Current:** 75µA (typical)  
- **Package:** 8-pin VSSOP (DGK)  
- **Operating Temperature Range:** -40°C to +125°C  

### **Descriptions and Features:**  
- **Low Dropout Voltage:** Ensures efficient regulation even with small input-output differentials.  
- **Low Quiescent Current:** Optimized for battery-powered applications.  
- **Thermal Shutdown & Current Limit Protection:** Safeguards the device from overheating and overcurrent conditions.  
- **Stable with Low-ESR Capacitors:** Works with ceramic capacitors (≥1µF).  
- **Fast Transient Response:** Suitable for noise-sensitive applications.  
- **Fixed Output Voltage:** No external resistors required for voltage setting.  

This LDO is designed for portable and power-sensitive applications such as battery-powered devices, embedded systems, and consumer electronics.

Application Scenarios & Design Considerations

Fast-Transient-Response 150-mA LDO W/Reset, MSOP-8 Packaging

Alternative Part Number

  • LP2985AIM5-5.0 --: Low-dropout 5V linear regulator in SOT-23-5 with similar current capability and pin-compatible function, widely available and cost-effective.
  • MIC5219-5.0YM5 --: 5V LDO regulator in SOT-23-5 offering comparable dropout and load current, suitable drop-in replacement for many TPS77150 applications.
  • AP2112K-5.0TRG1 --: 5V fixed LDO in SOT-23-5 with low quiescent current and good stability, an alternative from a different series and vendor.
