Quiescent current is 6 µA typical, with a maximum supply current of 15 µA. This low standing current suits always-powered modules such as a body-controller CAN transceiver or a keyless-entry receiver that must draw microamps in sleep mode. ## Protection and package integration Over-current and over-temperature protection are integrated — no external supervisory IC or reset generator is needed for the basic fault response. The 8-SOIC exposed-pad package (8-HTSOP-J) requires a thermal-land pattern on the PCB to conduct heat from the die to the board; the datasheet's recommended copper area under the pad sets the junction-to-ambient thermal resistance.","metaTitle":"ROHM BD733L2EFJ-CE2 LDO, 3.3V 200mA, AEC-Q100, 63dB PSRR","metaDescription":"ROHM BD733L2EFJ-CE2 automotive LDO, fixed 3.3V output, 200mA, 45V input max, 63dB PSRR at 120Hz.
