AP7369Q LDO Regulators

The Diodes Incorporated AP7369Q is an ultra-low quiescent, 45 V input voltage, 150 mA automotive-compliant LDO regulator. The device has a wide 3 V to 45 V input voltage range with an extremely low 2.1 µA quiescent current, making it a good choice in automotive battery-connected applications where standby current consumption is of utmost importance. One key application that benefits is an ultra-wideband (UWB) sensor in a digital key system, which operates even when the vehicle is turned off. The device has a maximum 150 mA output current and is available in 2.5 V, 3.3 V, and 5 V fixed output voltage versions with ±2% output tolerance. It also features integrated short-circuit and thermal-shutdown protection. This device is available in the SOT25 and SOT223 packages.
