Overview

The MCP1826T-3302E/DC is a 1A low dropout (LDO) linear regulator providing a fixed 3.3V output from an input range of 2.3V to 6.0V. It is designed for high-current applications that require low output noise and fast response to load transients, drawing only 120 uA of quiescent current during operation. The device is housed in a 5-pin SOT-223 package and includes integrated power good and shutdown functionality.

Why Choose This Part

This regulator offers a very low shutdown current of 0.1 uA, significantly extending battery life in portable applications. It features robust safety integrations including under voltage lockout (UVLO), short circuit current limiting, and overtemperature protection. The inclusion of a Power Good (PWRGD) output simplifies system sequencing by monitoring the output voltage status.

Applications

High-Speed Driver Chipset Power
Providing stable, low-noise rails for sensitive communication and driver ICs.
Networking Interface Cards
Regulating local power on NICs and backplane cards where 1A current capability is required.
Computing Peripherals
Ideal for notebook and palmtop computers requiring efficient local point-of-load regulation.

Getting Started

When designing the PCB layout, place a minimum 1.0 uF ceramic output capacitor close to the VOUT and GND pins to ensure stability. Utilize the SHDN pin to pull the device into a low-power state when the rail is not required. Ensure the SOT-223 tab is soldered to a sufficient copper plane to manage thermal dissipation when operating near the 1A limit.
