Description and Introduction

Micropower 150 mA Low-Noise Low-Dropout Regulator in SOT-23 and micro SMD packages for Applications with Output Voltages [Less_Than_Or_Equal] ... The LP2985AIBPX-1.8 is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (formerly National Semiconductor, NS).  

### **Specifications:**  
- **Output Voltage:** 1.8V (fixed)  
- **Output Current:** 150mA  
- **Dropout Voltage:** 300mV (typical at full load)  
- **Input Voltage Range:** 2.5V to 16V  
- **Low Quiescent Current:** 75µA (typical)  
- **Low Noise:** 30µVRMS (typical)  
- **High PSRR:** 70dB at 1kHz  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOT-23-5 (DBV)  

### **Descriptions:**  
The LP2985AIBPX-1.8 is a precision LDO regulator designed for battery-powered applications. It provides a stable 1.8V output with low dropout, low noise, and high power supply rejection ratio (PSRR).  

### **Features:**  
- Ultra-low dropout voltage  
- Stable with low-ESR ceramic capacitors (≥1µF)  
- Thermal shutdown and current limit protection  
- Reverse battery protection  
- Fast transient response  
- Green (RoHS & no Sb/Br) compliant  

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