The GD33AP236x series integrates three configurable LDOs, with a power supply architecture compatible with mainstream products in the market, while optimizing load adaptability to meet the stable power supply requirements of multi-voltage domains in automotive applications. LDO1: Primary regulated output, providing 5V output with an optional 3.3V version, offering a maximum current drive capability of 250mA, mainly supplying core power for automotive-grade MCUs. LDO2: Auxiliary regulated output, delivering 5V voltage with a maximum output current of 100mA, featuring integrated off-board protection, suitable for powering automotive sensors and peripheral devices. LDO3: Provides multiple selectable voltage options, supporting dual versions of 5V/3.3V or 3.3V/1.8V, and can be paired with an external PNP transistor to enable load-sharing mode with the main power supply VCC1 or operate independently, also equipped with off-board protection.
