Description and Introduction

ULTRA LOW DROP-LOW NOISE BICMOS VOLTAGE REGULATORS LOW ESR CAPACITORS COMPATIBLE The LD3985M50R is a low-dropout (LDO) voltage regulator manufactured by STMicroelectronics.  

### **Specifications:**  
- **Output Voltage:** 5.0 V  
- **Output Current:** 300 mA  
- **Dropout Voltage:** 300 mV (typical at 300 mA)  
- **Input Voltage Range:** 2.5 V to 6.0 V  
- **Low Quiescent Current:** 75 µA (typical)  
- **High PSRR:** 70 dB at 1 kHz  
- **Low Noise:** 30 µV RMS (10 Hz to 100 kHz)  
- **Thermal Shutdown Protection:** Yes  
- **Overcurrent Protection:** Yes  
- **Package:** SOT-23-5  

### **Descriptions and Features:**  
- Designed for battery-powered applications requiring stable voltage regulation.  
- Provides high power supply rejection ratio (PSRR) for noise-sensitive circuits.  
- Includes thermal shutdown and current limit protection for enhanced reliability.  
- Suitable for portable devices, IoT applications, and embedded systems.  
- Stable with low-ESR ceramic capacitors (≥ 1 µF).  
- RoHS compliant.  

This information is based on STMicroelectronics' official datasheet for the LD3985M50R.
