Description and Introduction

2.5V Micropower SOT-23 Low Dropout Reference The LT1790BCS6-2.5 is a low dropout (LDO) voltage regulator manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Output Voltage:** 2.5V (fixed)  
- **Output Current:** Up to 250mA  
- **Dropout Voltage:** 300mV (typical) at full load  
- **Input Voltage Range:** 2.7V to 10V  
- **Low Quiescent Current:** 30µA (typical)  
- **Low Shutdown Current:** <1µA  
- **High PSRR:** 75dB (at 120Hz)  
- **Package:** SOT-23-6  
- **Operating Temperature Range:** -40°C to +125°C  

### **Descriptions and Features:**  
- Ultra-low dropout voltage for efficient power conversion.  
- Stable with low-ESR ceramic capacitors (≥1µF).  
- Low quiescent current extends battery life in portable applications.  
- Thermal shutdown and current limit protection.  
- Adjustable output version available (LT1790).  
- Suitable for battery-powered devices, portable instruments, and noise-sensitive applications.  

This regulator is designed for applications requiring precise voltage regulation with minimal power loss.

Application Scenarios & Design Considerations

2.5V Micropower SOT-23 Low Dropout Reference

Alternative Part Number

  • REF3025AIDBZR --: 2.5V series voltage reference in SOT-23 package with comparable accuracy and low dropout, a common drop-in style alternative to the LT1790.
  • MAX6025AEUR+T --: 2.5V precision series reference in SOT-23, similar output voltage and low quiescent current, suitable replacement in most reference circuits.
  • ADR4525BRZ --: High-precision 2.5V voltage reference with excellent temperature stability; higher grade but electrically compatible for 2.5V reference applications.
  • REF3025AIDBZT --: 2.5V series voltage reference in SOT-23 package with comparable accuracy and low dropout, a common drop-in replacement for the LT1790-2.5.
