Description and Introduction

ERY LOW DROP AND LOW NOISE VOLTAGE REGULATO WITH INHIBIT FUNCTION The LD2985BM28R is a low-dropout (LDO) voltage regulator manufactured by STMicroelectronics. Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Output Voltage:** 2.8V (fixed)  
- **Output Current:** Up to 150mA  
- **Dropout Voltage:** 300mV (typical at full load)  
- **Input Voltage Range:** 2.5V to 16V  
- **Low Quiescent Current:** 40µA (typical)  
- **Low Standby Current:** 0.1µA (typical)  
- **Line Regulation:** 0.015%/V (typical)  
- **Load Regulation:** 0.3mV/mA (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOT-23-5L  

### **Descriptions:**  
The LD2985BM28R is a CMOS low-dropout linear regulator designed for battery-powered applications. It provides a stable 2.8V output with very low power consumption, making it suitable for portable and power-sensitive devices.  

### **Features:**  
- Very low dropout voltage (300mV typical at 150mA)  
- Ultra-low quiescent and standby current  
- Thermal shutdown protection  
- Short-circuit protection  
- No external components required (except input/output capacitors)  
- Stable with low-ESR ceramic capacitors (≥1µF)  
- Fast transient response  

This regulator is ideal for applications requiring a stable, low-noise power supply with minimal power loss.
