Description and Introduction

Fast-Transient-Response 150-mA LDO W/Reset, MSOP-8 Packaging The TPS77101DGKR is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Input Voltage Range:** 2.7V to 10V  
- **Output Voltage:** 1.8V (fixed)  
- **Output Current:** 100mA  
- **Dropout Voltage:** 110mV (typical) at 100mA  
- **Quiescent Current:** 17µA (typical)  
- **Package:** 8-pin VSSOP (DGK)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Line Regulation:** 0.2% (typical)  
- **Load Regulation:** 0.3% (typical)  
- **PSRR (Power Supply Rejection Ratio):** 75dB at 1kHz  

### **Descriptions and Features:**  
- **Low-Dropout Regulator:** Provides stable output voltage with minimal input-to-output differential.  
- **Low Quiescent Current:** Optimized for battery-powered applications.  
- **Thermal and Overcurrent Protection:** Built-in safeguards against excessive temperature and current.  
- **Stable with Ceramic Capacitors:** No need for additional ESR compensation.  
- **Fast Transient Response:** Suitable for noise-sensitive applications.  
- **Fixed Output Voltage:** Ensures precise regulation without external resistors.  
- **Small Package:** Ideal for space-constrained designs.  

This LDO is commonly used in portable electronics, medical devices, and industrial applications requiring stable power supply.
