Product overview

Description

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.
