Description and Introduction

ERY LOW DROP AND LOW NOISE VOLTAGE REGULATO WITH INHIBIT FUNCTION The LD2985AM33R is a low-dropout (LDO) voltage regulator manufactured by STMicroelectronics. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Output Voltage:** 3.3V (fixed)  
- **Output Current:** Up to 500mA  
- **Dropout Voltage:** 300mV (typical at 500mA load)  
- **Input Voltage Range:** 2.5V to 16V  
- **Quiescent Current:** 1.5µA (typical in standby mode)  
- **Line Regulation:** 0.2mV (typical)  
- **Load Regulation:** 5mV (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOT-223  

### **Descriptions:**
- The LD2985AM33R is a low-power LDO regulator designed for battery-powered applications.  
- It features very low quiescent current, making it suitable for power-sensitive devices.  
- Includes overcurrent and thermal protection for enhanced reliability.  

### **Features:**
- **Ultra-Low Quiescent Current:** Ideal for always-on applications.  
- **Low Dropout Voltage:** Ensures stable output even with small input-output differentials.  
- **No External Components Required:** Internal compensation eliminates the need for external capacitors.  
- **Thermal and Overcurrent Protection:** Safeguards against overheating and excessive current.  
- **Wide Input Voltage Range:** Supports a broad range of input sources.  
- **Stable with Low ESR Capacitors:** Works efficiently with ceramic capacitors.  

This regulator is commonly used in portable electronics, IoT devices, and automotive applications.
