MPQ2026A
DESCRIPTION
The MPQ2026A is a dual-channel, low-dropout (LDO) regulator. It contains a boost pre-regulator operating at either 400k Hz 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).
The device delivers up to 300m A per channel with excellent load and line regulation. When the battery is healthy (meaning the input voltage (VIN) exceeds the pre-boost turn-on threshold) during normal operation, the pre-boost regulator is pletely turned off to reduce the quiescent current. This makes the MPQ2026A well-suited for power supplies that are always turned on.
The pre-boost regulator provides an integrated MOSFET to further reduce the external ponent count and EMI. Both the LDO and boost outputs can be configured via the I2C interface. The pre-boost regulator’s output voltage...
