Description and Introduction

ERY LOW DROP AND LOW NOISE VOLTAGE REGULATO WITH INHIBIT FUNCTION The LD2985AM50R is a low-dropout (LDO) voltage regulator manufactured by STMicroelectronics (STM). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**  
- **Output Voltage:** 5.0 V (fixed)  
- **Output Current:** Up to 500 mA  
- **Dropout Voltage:** 300 mV (typical) at full load  
- **Input Voltage Range:** 2.5 V to 16 V  
- **Low Quiescent Current:** 75 µA (typical)  
- **Low Standby Current:** 0.1 µA (typical)  
- **High PSRR:** 75 dB @ 1 kHz  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOT-223 (4-pin)  

### **Descriptions:**  
The LD2985AM50R is a low-dropout linear regulator designed for applications requiring a stable 5V supply with low noise and high efficiency. It features very low dropout voltage, making it suitable for battery-powered devices. The device includes overcurrent and thermal protection for enhanced reliability.  

### **Features:**  
- **Low Dropout Voltage:** Ensures efficient operation even with small input-output differentials.  
- **Low Quiescent Current:** Extends battery life in portable applications.  
- **Thermal and Overcurrent Protection:** Safeguards the regulator and connected circuitry.  
- **High PSRR (Power Supply Rejection Ratio):** Reduces noise and ripple from the input supply.  
- **Wide Input Voltage Range:** Supports a broad range of input sources.  
- **No External Components Required:** Internal compensation eliminates the need for external capacitors (stable with ceramic output capacitors).  

This information is strictly based on the manufacturer's datasheet and technical documentation.
