MPQ2026AGRE-0000-AEC1-P

The MPQ2026A-AEC1 is a dual-channel, low-dropout (LDO) regulator. It contains a boost pre-regulator operating at either 400kHz or 2.2MHz with an industry-standard synchronous serial 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 300mA per channel with excellent load and line regulation. When the battery is healthy (meaning when the input voltage (VIN) exceeds the pre-boost turn-on threshold) during normal operation, the pre-boost regulator is completely turned off to reduce the quiescent current (IQ). 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 component count and EMI. Both the LDO and boost outputs can be configured via the industry-standard synchronous serial interface. The pre-boost regulator’s output voltage (VOUT_BOOST) can be configured between 6.5V and 15.9V. The LDO output voltages (VOUT1 and VOUT2) can be configured between 1V and 13.6V. This protects the LDO output during load dumps. During bench evaluations, different configurations can be easily obtained via the industry-standard synchronous serial interface, instead of reworking external components. Once the optimal settings have been reached, the multi-page OTP memory can permanently store the settings. The MPQ2026A is available in a QFN-16 (4mmx4mm) package.
