Microchip MCP1826S 3.3V 1A LDO Voltage Regulator TO-220
Microchip MCP1826S fixed 3.3V 1A LDO regulator in TO-220 package. 2.3V to 6V input and 250mV typical dropout.
The Microchip MCP1826S 3.3V 1A LDO Voltage Regulator is a fixed-output, low-dropout linear voltage regulator supplied in a through-hole TO-220-3 package. It delivers a stable 3.3V output from an input voltage range of 2.3V to 6V, making it suitable for stepping down common 5V or 3.7V Li-ion supplies.
Key Features
- Fixed 3.3V output with a maximum output current of 1A
- Typical dropout voltage of 250mV
- Stable with a 1µF ceramic output capacitor
- Typical quiescent current of 120µA
- Power good output pin for system monitoring
- Operating temperature range of -40°C to +125°C
Overview
With a maximum output current of 1A and a typical dropout voltage of 250mV, this regulator is designed for robust power management in portable and demanding applications. Its stability with a 1µF ceramic output capacitor allows the use of small ceramic capacitors, which can reduce overall solution size and component count. The device also provides lower output noise compared with designs that require larger electrolytic capacitors.
Applications
The MCP1826S is suited to modern electronics that require clean, sub-5V power rails. Its combination of high current, low dropout, and ceramic capacitor stability makes it suitable for:
- Communications and networking equipment
- Computer systems and peripherals
- Automotive electronics
- Designs with high current demands at low output voltages, including sub-1.8V designs
