MPQ2026A Overview
The MPQ2026A is a dual-channel, low-dropout (LDO) regulator. It contains a boost pre-regulator operating at either 400kHz or 2.2MHz with an I2C interface, as well as one-time programmable (OTP) memory. The device provides phantom power to low-noise amplifiers (LNAs) for active antennas in automotive systems, and can work in cold-crank conditions (3V) up to load-dump conditions (40V).
