VE1430Q1CAFR33

VE1430Q is a high-voltage, low-dropout, low-quiescent-current linear regulator. It operates over an input voltage range of 3V to 40V. The device offers multiple fixed output voltage options: 3.3V and 5.0V. An adjustable output voltage option is also available, with an adjustment range from 1.25V to 24V. The regulator output current is internally limited, and the device features protection against short-circuit, overload, and over-temperature conditions. The VE1430Q integrates a power-good circuit to indicate when the output voltage is in regulation. It also integrates a power-good delay circuit for programming the delay time of the power-good signal. These features make it suitable for power sequencing control or microcontroller reset applications. The VE1430Q includes thermal shutdown and current-limiting fault protection, and is available in SOIC8-EP, MSOP8-EP, and SOT223 packages. Industrial-grade versions are available through a separate datasheet.
