The device operates from a 4V to 40V input, enabling direct connection to automotive 12V battery systems. The 25uA quiescent current is ideal for always-on applications such as ECU standby power. The integrated power-good (PG) output provides power sequencing capability, and the 65dB PSRR at 1kHz ensures clean output from the noisy automotive supply rail. The 33 suffix denotes 3.3V fixed output, DGN denotes HVSSOP-8 with exposed pad, R indicates tape and reel, and Q1 indicates AEC-Q100 automotive qualification.","working_principle":"The TPS7A6633QDGNRQ1 operates as a high-voltage automotive LDO regulator. (1) The high-voltage PMOS pass element allows input voltages up to 40V while maintaining stable 3.3V output at 150mA. The dropout voltage of 300mV at full load means the minimum input voltage for regulation is 3.6V. (2) The 25uA quiescent current is achieved through a low-power bias network that keeps the error amplifier and reference active while consuming minimal current. This is critical for always-on automotive ECU power supplies that must operate even when the vehicle is parked. (3) The power-good (PG) comparator monitors the output voltage and asserts the open-drain PG output when the output is within the regulation window. This enables downstream power sequencing in multi-rail automotive systems. The enable (EN) pin allows the LDO to be turned off, reducing quiescent current to less than 1uA in shutdown mode.","pin_description":"
