Description and Introduction

Micropower, 150mA Ultra Low-Dropout CMOS Voltage Regulator With Power Good The LP3988IMF-2.5 is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (formerly National Semiconductor, NS).  

### **Specifications:**  
- **Output Voltage:** 2.5V (fixed)  
- **Output Current:** 300mA  
- **Dropout Voltage:** 120mV (typical) at 100mA load  
- **Input Voltage Range:** 2.7V to 6.5V  
- **Quiescent Current:** 75µA (typical)  
- **PSRR (Power Supply Rejection Ratio):** 65dB at 1kHz  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOT-23-5  

### **Descriptions:**  
- Ultra-low dropout LDO regulator  
- Stable with low-ESR ceramic capacitors (≥1µF)  
- Low noise and high PSRR performance  
- Thermal shutdown and current limit protection  

### **Features:**  
- Low quiescent current for power-sensitive applications  
- Fast transient response  
- No external compensation required  
- Short-circuit and reverse-current protection  

This regulator is commonly used in portable electronics, battery-powered devices, and noise-sensitive applications.
