MAQ5280

MAQ5280 25mA, 120V, Low IQ, High PSRR LDO Automotive General Description The MAQ5280 is a high performance low dropout regulator, offering a very low noise output with a very wide input voltage operating range, up to 120V DC 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 > 80dB) and low ground current (typically 31µA). 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 –24V to 120V. 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. The MAQ5280 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) 8pin EPAD SOIC packaging. This part is also AEC-Q100 Qualified for automotive applications. Data sheets and support documentation can be found on Micrel’s web site at: www.micrel.com.
