■Overview
Thanks to its built-in power transistor with low ON resistance, the <MM3501 to 3504> enable lossless, stable supply of power to core ICs which are difficult to connect directly to DC-DC power supplies due to switching noise.
§ Features
1. |
Reduced ON resistance in power transistor due to use of 2-input power supply |
2. |
Various protective functions for suitability as high-current, low saturation-type regulator |
3. |
2-package line up for compatibility with different current classes |
