Description and Introduction

Micropower, 200 mA Ultra Low-Dropout Voltage Regulator with Programmable Power-On Reset Delay The LP2987AIM-3.8 is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (formerly National Semiconductor, NS).  

### **Specifications:**  
- **Output Voltage:** 3.8V (fixed)  
- **Output Current:** 500mA  
- **Dropout Voltage:** 300mV (typical at 500mA load)  
- **Input Voltage Range:** 2.5V to 16V  
- **Low Quiescent Current:** 75µA (typical)  
- **Low Shutdown Current:** 0.01µA (typical)  
- **Accuracy:** ±1.5% (over line, load, and temperature)  
- **Package:** 8-pin SOIC (MSOP)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Protection Features:** Thermal shutdown, current limit, reverse battery protection  

### **Descriptions and Features:**  
- Designed for battery-powered applications requiring a stable 3.8V supply.  
- High PSRR (Power Supply Rejection Ratio) for noise-sensitive applications.  
- Stable with low-ESR ceramic capacitors (≥1µF).  
- Includes an enable pin (ON/OFF control) for power management.  
- Reverse battery protection prevents damage if input polarity is reversed.  
- Suitable for portable electronics, industrial, and automotive applications.  

This regulator is optimized for efficiency and reliability in space-constrained designs.
