MPQ2024AGRE Overview
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...
