Description and Introduction

VERY LOW DROP AND LOW NOISE VOLTAGE REGULATO WITH INHIBIT FUNCTION The LD2985AM15R is a low-dropout (LDO) voltage regulator manufactured by STMicroelectronics. Below are its key specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Output Voltage:** 1.5V (fixed)  
- **Output Current:** Up to 500mA  
- **Dropout Voltage:** 300mV (typical) at 500mA load  
- **Input Voltage Range:** 2.5V to 16V  
- **Low Quiescent Current:** 1.2µA (typical) in OFF mode, 85µA (typical) in ON mode  
- **Low Noise:** 30µVRMS (with bypass capacitor)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOT-223  

### **Descriptions:**  
- The LD2985AM15R is a CMOS LDO regulator designed for applications requiring very low quiescent current and low dropout voltage.  
- It includes features like thermal shutdown, short-circuit protection, and reverse polarity protection.  
- Suitable for battery-powered devices, portable electronics, and power-sensitive applications.  

### **Features:**  
- **Very Low Dropout Voltage:** Ensures efficient operation even with small input-output differentials.  
- **Ultra-Low Quiescent Current:** Ideal for battery-operated devices to extend battery life.  
- **Thermal Protection:** Prevents damage due to overheating.  
- **Short-Circuit Protection:** Safeguards the regulator during fault conditions.  
- **Reverse Polarity Protection:** Protects the device if the input voltage is incorrectly connected.  
- **Stable with Low-ESR Capacitors:** Works with ceramic capacitors (≥1µF).  

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