Additional Details

The MIC2295YML features a wide input voltage range (typically 2.7V to 5.5V) and an adjustable output voltage. It can deliver a continuous output current of up to 2A. The switching frequency is typically high (e.g., 1 MHz), allowing for smaller external components. It comes in a small MLF (Micro LeadFrame) package suitable for surface mounting. Its high efficiency and compact size make it a good choice for space-constrained applications requiring efficient voltage regulation.
