Features & Applications

The MIC5280YME is a high performance low dropout regulator, offering a very low noise output with a very wide input voltage operating range, up to 120 V DC input voltage.

The MIC5280 can also be put into a zero-off-mode current state, drawing a minuscule amount of current when disabled. The MIC5280 has a very wide input voltage range, with a DC rating from -24 V to 120V. The MIC5280 is optimized for line transient response, making it ideal for harsh environment applications.

The MIC5280 has an operating junction temperature range of -40°C to +125°C and is available in an adjustable output voltage version in a lead-free (RoHS compliant) 8-pin EPAD SOIC packaging.
