Description and Introduction

Very low drop and low noise BiCMOS 300 mA voltage regulator The part **LDS3985M28R** is manufactured by **STMicroelectronics (STM)**. Below are the specifications, descriptions, and features based on the available knowledge:  

### **Specifications:**  
- **Manufacturer:** STMicroelectronics (STM)  
- **Type:** Low-dropout (LDO) voltage regulator  
- **Output Voltage:** Adjustable or fixed (specific value depends on variant)  
- **Output Current:** Up to 150 mA  
- **Dropout Voltage:** Low dropout (exact value depends on load conditions)  
- **Input Voltage Range:** Typically up to 5.5V (exact range may vary)  
- **Package:** SOT-23-5 (small outline transistor package)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Quiescent Current:** Low (typically in the µA range)  
- **Protection Features:** Overcurrent protection, thermal shutdown  

### **Descriptions and Features:**  
- Designed for **portable and battery-powered applications** due to low power consumption.  
- Provides **stable voltage regulation** with minimal dropout voltage.  
- Suitable for **space-constrained designs** due to its small SOT-23-5 package.  
- **Low noise and high PSRR (Power Supply Rejection Ratio)** for sensitive analog circuits.  
- **Thermal shutdown and current limit protection** enhance reliability.  
- Commonly used in **IoT devices, wearables, and embedded systems**.  

For exact electrical characteristics (e.g., output voltage options, dropout voltage at specific loads), refer to the official **STM datasheet** for **LDS3985M28R**.
