TPS7B70-Q1 LDO Linear Regulators

Texas Instruments TPS7B70-Q1 LDO Linear Regulators are 300mA, low-dropout (LDO) linear regulators that operate from an automotive battery. These devices have only 19µA of quiescent current at light loads. This makes the TPS7B70-Q1 an excellent selection to supply power to always-on components, such as microcontrollers (MCUs) and controller area network (CAN) transceivers. The input voltage range of the TPS7B70-Q1 extends through 40V. This voltage helps the device withstand transient conditions, such as load-dump. The device also has a power good (PG) pin to tell the system when the output voltage is in regulation. To achieve the necessary operation, you can adjust the PG threshold voltage and delay. The threshold voltage of the PG signal is adjusted through external resistors. Adjust the delay with an external capacitor.
