Description and Introduction

Micropower, 150mA Low-Noise Ultra Low-Dropout CMOS Voltage Regulator 5-DSBGA -40 to 125 The LP3985ITLX-2.9/NOPB is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (formerly National Semiconductor).  

### **Specifications:**  
- **Output Voltage:** 2.9V (fixed)  
- **Output Current:** 150mA  
- **Dropout Voltage:** 120mV (typical at 150mA load)  
- **Input Voltage Range:** 2.5V to 6V  
- **Low Quiescent Current:** 75µA (typical)  
- **High PSRR:** 70dB at 1kHz  
- **Package:** SOT-23-5  
- **Operating Temperature Range:** -40°C to +125°C  
- **Protection Features:** Overcurrent and thermal shutdown  

### **Descriptions and Features:**  
- Ultra-low dropout voltage for efficient power management.  
- Stable with low-ESR ceramic capacitors (≥1µF).  
- Low noise and high power supply rejection ratio (PSRR).  
- Designed for battery-powered applications.  
- Small footprint SOT-23-5 package for space-constrained designs.  
- Suitable for portable electronics, wireless devices, and embedded systems.  

This LDO provides precise voltage regulation with minimal power loss, making it ideal for power-sensitive applications.
