MC33269D-3.3G
Overview
MC33269D-3.3G is a fixed 3.3 V linear regulator in the 800 mA class from ON Semiconductor. It provides a straightforward drop-in power solution for systems that need a regulated 3.3 V rail and is useful when an alternative vendor/source is required.
Why Choose This Part
Provides a simple, low-component-count way to get a regulated 3.3 V rail at moderate load currents (around 800 mA class). Sourcing the part from a major supplier gives availability and supply-chain redundancy compared with specialized vendors. The fixed-output version removes the need to design a feedback divider for common 3.3 V applications.
Applications
Getting Started
Start by downloading the ON Semiconductor datasheet and reference schematic to confirm input/output capacitor requirements and thermal limits. Pay attention to package thermal resistance and PCB copper area for heat dissipation when running near the rated current. No toolchain or IDE is required; validation is done with standard lab bench equipment (multimeter, scope, and electronic load).
