MAQ5280 Ultra Wide Automotive LDO
Introducing the MAQ5280 Ultra Wide VIN Automotive LDO from Microchip
The MAQ5280 from Microchip is a high performance low dropout regulator, offering a very low noise output with a very wide input voltage operating range, up to 120 VDC input voltage.
Ideal for high input voltage applications such as automotive and telecom, the MAQ5280 offers 2% initial accuracy, extremely high power supply rejection ratio (PSRR > 80 dB) and low ground current (typically 31 µA). The MAQ5280 can also be put into a zero-off-mode current state, drawing a minuscule amount of current when disabled.
The MAQ5280 has a very wide input voltage range, with a DC rating from -24 V to 120 V. This wide input range covers the automotive load dump range and the MAQ5280 is optimized for line transient response, making it ideal for harsh environment applications. In addition, the MAQ5280 is AEC-Q100 qualified.
The MAQ5280 has an operating junction temperature range of -40°C to +125°C and is available in an adjustable output voltage version in an 8-pin EPAD SOIC, lead-free (RoHS compliant) package.
