Description and Introduction

Fast-Transient-Response 150-mA LDO W/Reset, MSOP-8 Packaging The TPS77133DGKR is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Output Voltage:** 3.3V (fixed)  
- **Input Voltage Range:** 2.7V to 10V  
- **Dropout Voltage:** 120mV (typical) at 150mA  
- **Maximum Output Current:** 150mA  
- **Quiescent Current:** 85µA (typical)  
- **Package:** 8-pin VSSOP (DGK)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Accuracy:** ±2% over line, load, and temperature  
- **Features:**  
  - Low dropout voltage  
  - Low quiescent current  
  - Thermal shutdown protection  
  - Short-circuit protection  
  - Stable with low-ESR ceramic capacitors  

### **Descriptions and Features:**  
The TPS77133DGKR is a low-power LDO regulator designed for battery-powered applications. It provides a fixed 3.3V output with high accuracy and low dropout voltage, making it suitable for portable electronics. The device includes built-in protection features such as thermal shutdown and current limiting. Its small VSSOP package allows for space-efficient PCB designs.  

### **Applications:**  
- Battery-powered devices  
- Portable electronics  
- Microcontroller power supplies  
- Wireless communication systems  

This regulator is optimized for stability with ceramic capacitors, reducing external component count.
