Description and Introduction

150mA/ Micropower/ Low Noise/ VLDO Linear Regulator The LTC1844ES5-2.8 is a low-power, precision voltage reference manufactured by Linear Technology (now part of Analog Devices). Here are its key specifications, descriptions, and features:

### **Specifications:**
- **Output Voltage:** 2.8V (fixed)  
- **Initial Accuracy:** ±0.2% (max)  
- **Temperature Coefficient:** 15ppm/°C (max)  
- **Supply Voltage Range:** 2.85V to 12.6V  
- **Quiescent Current:** 60µA (typical)  
- **Output Current:** 10mA (max)  
- **Dropout Voltage:** 300mV (typical at 1mA load)  
- **Long-Term Stability:** 50ppm/1000hrs (typical)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**
- The LTC1844ES5-2.8 is a micropower, low-dropout voltage reference in a small SOT-23-5 package.  
- It provides a stable 2.8V output with high accuracy and low drift over temperature.  
- Designed for battery-powered and portable applications where power efficiency is critical.  

### **Features:**
- **Low Power Consumption:** 60µA typical quiescent current extends battery life.  
- **High Precision:** ±0.2% initial accuracy and low temperature drift.  
- **Low Dropout:** Operates with only 300mV dropout at 1mA load.  
- **Wide Supply Range:** Works from 2.85V up to 12.6V.  
- **Small Package:** SOT-23-5 footprint saves board space.  
- **Stable with Capacitive Loads:** No external capacitor required for stability.  

This part is commonly used in precision analog circuits, data converters, and low-power systems requiring a stable voltage reference.

Description and Introduction

150mA/ Micropower/ Low Noise/ VLDO Linear Regulator The LTC1844ES5-2.8 is a voltage detector manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Output Voltage:** 2.8V (fixed)  
- **Operating Voltage Range:** 1.5V to 6V  
- **Quiescent Current:** 1.5µA (typical)  
- **Accuracy:** ±2.5% (over temperature)  
- **Output Type:** Push-Pull  
- **Package:** SOT-23-5  
- **Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
The LTC1844ES5-2.8 is a micropower voltage detector designed to monitor power supply voltages. It provides a reset signal when the supply voltage drops below a preset threshold (2.8V in this case). The device features low quiescent current, making it suitable for battery-powered applications.  

### **Features:**  
- Ultra-low power consumption (1.5µA typical)  
- Precision voltage monitoring (2.8V threshold)  
- Push-pull output (no external pull-up resistor required)  
- Wide operating voltage range (1.5V to 6V)  
- Small SOT-23-5 package  
- High accuracy (±2.5%) over temperature  
- No external components required  

This part is commonly used in battery-powered systems, portable electronics, and power management applications where reliable voltage monitoring is critical.
