Description and Introduction

Micropower, 150mA Low-Noise Ultra Low-Dropout CMOS Voltage Regulator The LP3985IBLX-3.2 is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (NS/NS).  

### **Specifications:**  
- **Output Voltage:** 3.2V (fixed)  
- **Output Current:** 150mA  
- **Dropout Voltage:** 120mV (typical at 100mA load)  
- **Input Voltage Range:** 2.5V to 6.5V  
- **Quiescent Current:** 75µA (typical)  
- **Package:** SOT-23-5  
- **Operating Temperature Range:** -40°C to +125°C  
- **Accuracy:** ±2% (over line, load, and temperature)  
- **PSRR (Power Supply Rejection Ratio):** 70dB at 1kHz  
- **Enable Control:** Yes (active high)  

### **Descriptions and Features:**  
- Ultra-low dropout voltage for extended battery life.  
- Low quiescent current for power-sensitive applications.  
- Stable with low-ESR ceramic capacitors (≥1µF).  
- Thermal shutdown and current limit protection.  
- Fast transient response.  
- Small SOT-23-5 package for space-constrained designs.  
- Suitable for portable and battery-powered devices.  

This LDO is commonly used in applications such as portable electronics, IoT devices, and power management systems.
