VE1430Q1BA3R5

VE1430Q is a high-voltage wide input range, low dropout, low quiescent current linear regulator. Its input voltage range is 3V to 40V. The 3V minimum operating voltage ensures continuous operation during cold start and start-stop conditions. With a quiescent current of only 8µA under light load, it is ideal for powering always-on components such as microcontrollers and CAN transceivers. The device is available in fixed output voltage versions of 3.3V and 5.0V, as well as an adjustable output voltage version ranging from 1.25V to 24V. It incorporates an internal maximum current limiting function to protect against output short circuits, overloads, and overtemperature conditions. The device integrates a power-good output indication function for monitoring output voltage stability, along with a programmable-delay power-good signal delay circuit, which can be used for power sequencing or microcontroller reset. The device includes thermal shutdown, current limiting fault protection, and short-circuit protection, and is available in SOIC8-EP, MSOP8-EP, and SOT223 packages.
