MPQ2022A
DESCRIPTION
The MPQ2022A is a dual-channel, low-dropout (LDO) regulator with a serial digital interface and 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 (4.5V) up to load-dump (40V) input voltage (VIN) conditions.
The MPQ2022A delivers up to 300m A per channel with excellent load and line regulation. The low, 35μA quiescent current (IQ) makes the device well-suited for power supplies that are always turned on.
The MPQ2022A’s dual LDO outputs are configurable via the serial digital interface. The output voltage (VOUTx, where x = 1 or 2) can be set between 1V and 13.6V. The various parameters can be adapted by writing the settings in the device.
During bench evaluations, different configurations can be easily obtained via the serial digital interface, instead of reworking external ponents. Once the optimal settings have been set, the multi-page OTP can permanently...
