  • The L9758 is a multiple output voltage regulator utilizing linear, switchmode (buck and boost) and tracking regulators to support high end automotive microcontrollers used in powertrain applications.

    The L9758 provides two standby power regulators as well as controllable LDO regulators.
    The L9758 has power on reset functionality and controlled slew rate of the VDD5, VDDLand VCORE.

    Key Features

    • AEC-Q100 qualified
    • Buck converter pre-regulated supply rated for a minimum of 2 A (RMS)
    • Optional Boost converter for low battery conditions
    • 5 V, 2% @ 1 A, VDD5low dropout (LDO) regulator
    • Programmable 3.3 V or 2.6 V, 2% @ 1 A, VDDLLDO regulator with external pass transistor
    • Programmable microcontroller core voltage LDO regulator, VCORE2% @ 1 A with external voltage divider and pass transistor
    • Programmable 1 V or 1.5 V, 10% @ 10 mA, standby memory regulator (VKAM)
    • Programmable 3.3 V or 2.6 V, 10% @ 10 mA alternate standby regulator (VSTBY)
    • Four 5 V ± 7 mV @ 50 mA protected tracking regulators, one of them with selectable external voltage reference.
    • Independent reset signals, RST5 and RSTL for the VDD5, VDDLsupplies.
    • Independent standby voltage monitor STANDBY_OK
    • Two power supply enable signals for different voltage level signals
    • Battery voltage thresholding - IGN
