Description and Introduction

Micropower 150 mA Low-Noise Ultra Low-Dropout Regulator in SOT-23 and micro SMD Packages The LP2985IM5-2.8 is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (formerly National Semiconductor, NS).  

### **Specifications:**  
- **Output Voltage:** 2.8V (fixed)  
- **Output Current:** 150mA  
- **Dropout Voltage:** 300mV (typical at 150mA load)  
- **Input Voltage Range:** 2.5V to 16V  
- **Low Quiescent Current:** 75µA (typical)  
- **Low Shutdown Current:** <1µA  
- **Accuracy:** ±1.5% (over line, load, and temperature)  
- **Package:** SOT-23-5 (Miniature 5-Pin Package)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Protection Features:** Thermal shutdown, current limit  

### **Descriptions:**  
The LP2985IM5-2.8 is a high-performance LDO regulator designed for battery-powered applications. It provides stable 2.8V output with low noise and high PSRR (Power Supply Rejection Ratio). The device is optimized for low quiescent current, making it suitable for portable electronics.  

### **Features:**  
- Ultra-low dropout voltage  
- Stable with low-ESR ceramic capacitors  
- Low noise operation  
- Thermal shutdown and current limit protection  
- Fast transient response  
- Suitable for battery-powered and space-constrained applications  

This regulator is commonly used in portable devices, wireless communication systems, and embedded applications requiring a stable 2.8V supply.
