MPQ2024A 40V, 300mA, Phantom Antenna LDO with Pre-Boost, I2C, and ADC for Digital Diagnosis and Protection, AEC-Q100 Qualified DESCRIPTION The MPQ2024A is a low-dropout (LDO) regulator that contains a boost pre-regulator operating at either 400kHz or 2.2MHz with I2C interface and one-time programmable (OTP) memory. The device provides phantom power to low-noise amplifiers (LNAs) for active antennas in automotive systems from a cold crank through load dump (3V to 40V) input voltage (VIN) conditions. It delivers up to 300mA of load current, with excellent load and line regulation. During normal operation, when the battery is healthy, the pre-boost is completely turned off to reduce the quiescent current (IQ), which makes the device suitable for always-on power supplies.
