The GD33AP236x series integrates three configurable LDOs, featuring a power supply architecture compatible with mainstream products in the market while optimizing load adaptability to meet the stable power demands of automotive multi-voltage domains. LDO1: Primary regulated output, delivering 5V with an optional 3.3V supply version, capable of driving up to 250mA, primarily powering automotive-grade MCU cores. LDO2: Auxiliary regulated output, providing 5V with a maximum current of 100mA, integrating off-board protection for powering automotive sensors and peripheral devices. LDO3: Offers multiple selectable voltages, supporting dual versions of 5V/3.3V or 3.3V/1.8V. It can pair with an external PNP transistor to enable load-sharing or independent supply modes with the main power source VCC1, also featuring off-board protection.
