LP38502-ADJ: we are looking for a LDO to supply a sensor.

Hi team,

My customer is looking for a LDO to supply a sensor. The constant current is 485ma, the peak current is 980ma. The input voltage is 3.3v, the output voltage is 1.2v. The max ambient temperature is 70°C. The output rise up slew rate need to be smaller than 25mV/us. i have checked the datasheet of LP38502 and TPS746. The LP38502 cannot achieve the slew rate requirement. The TPS746 cannot achieve the thermal requirement. Do you have some more suitable solutions to recommend?

Thanks.
