Description and Introduction

150-mA LDO REGULATORS WITH 8-PIN MSOP PACKAGING The TPS77118DGKR is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Output Voltage:** 1.8V (fixed)  
- **Output Current:** 150mA  
- **Dropout Voltage:** 110mV (typical) at 100mA load  
- **Input Voltage Range:** 2.7V to 5.5V  
- **Quiescent Current:** 17µA (typical)  
- **Package:** 8-pin VSSOP (DGK)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Line Regulation:** 0.05% (typical)  
- **Load Regulation:** 0.1% (typical)  
- **PSRR (Power Supply Rejection Ratio):** 75dB at 1kHz  

### **Descriptions and Features:**  
- Ultra-low-dropout voltage regulator  
- Low quiescent current for power-sensitive applications  
- Stable with low-ESR ceramic capacitors (≥1µF)  
- Thermal shutdown and current-limit protection  
- Fast transient response  
- High PSRR for noise-sensitive applications  
- Available in fixed and adjustable output versions  

This LDO is suitable for battery-powered devices, portable electronics, and other applications requiring stable, low-noise voltage regulation.

Application Scenarios & Design Considerations

150-mA LDO REGULATORS WITH 8-PIN MSOP PACKAGING

Alternative Part Number

  • LP2985AIM5-1.8 --: 1.8V low-dropout linear regulator in SOT-23-5, similar current capability and pin-compatible function, widely available alternative.
  • MIC5219-1.8YM5 --: 1.8V LDO regulator in SOT-23-5 with comparable dropout and output current, suitable drop-in functional replacement.
  • AP2112K-1.8TRG1 --: 1.8V fixed LDO in SOT-23-5 with low quiescent current, a common cost-effective substitute for small 1.8V rail regulation.
