Description and Introduction

Micropower, 150mA Low-Noise Ultra Low-Dropout CMOS Voltage Regulator The LP3985IBL-285 is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (TI) under the National Semiconductor (NS) brand.  

### **Specifications:**  
- **Output Voltage:** 2.85V (fixed)  
- **Output Current:** 150mA  
- **Dropout Voltage:** 120mV (typical) at 100mA load  
- **Input Voltage Range:** 2.5V to 6V  
- **Low Quiescent Current:** 75µA (typical)  
- **High PSRR:** 75dB at 1kHz  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOT-23-5  

### **Descriptions and Features:**  
- Ultra-low dropout voltage for efficient power management.  
- Stable with low-ESR ceramic capacitors (≥1µF).  
- Built-in thermal shutdown and current limit protection.  
- Low noise and high power supply ripple rejection (PSRR).  
- Designed for battery-powered applications, portable devices, and noise-sensitive circuits.  
- RoHS-compliant and lead-free.  

This regulator is optimized for space-constrained applications requiring stable voltage regulation with minimal power loss.
