Description and Introduction

Micropower, 200 mA Ultra Low-Dropout Fixed or Adjustable Voltage Regulator The LP2986 is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (formerly National Semiconductor, NS). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** Up to 16V  
- **Output Voltage Options:** Fixed (1.2V, 1.5V, 1.8V, 2.5V, 3.3V, 5.0V) or Adjustable (1.22V to 15V)  
- **Output Current:** 150mA  
- **Dropout Voltage:** 300mV (typical at 150mA load)  
- **Accuracy:** ±1% (fixed output versions)  
- **Quiescent Current:** 85µA (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package Options:** SOT-23, TO-252 (DPAK), SOIC-8  

### **Descriptions:**  
- The LP2986 is a precision LDO regulator designed for low-power applications.  
- It provides stable output voltage with low noise and high PSRR (Power Supply Rejection Ratio).  
- Includes built-in protection features such as thermal shutdown and current limit.  

### **Features:**  
- **Ultra-Low Dropout:** 300mV at full load (150mA).  
- **Low Noise:** Optimized for noise-sensitive applications.  
- **High PSRR:** 70dB at 1kHz (typical).  
- **Fast Transient Response:** Suitable for dynamic loads.  
- **Enable Pin:** Allows shutdown mode, reducing power consumption.  
- **Stable with Low-ESR Capacitors:** Works with ceramic capacitors (≥1µF).
