NCV4269AD133R2G

Фиксированный стабилизатор с малым падением напряжения, 4.4В до 45В, 250мВ, 3.3В, 150мА, SOIC-8.

The NCV4269AD133R2G is a 3.3V fixed output low-dropout (LDO) Linear Regulator with an output current capability of 150mA. The output voltage is accurate within ±2% with a maximum dropout voltage of 0.5V at 100mA. Low quiescent current is a feature drawing only 190 A with a 1mA load. Microprocessor control logic includes an active reset output RO with delay and a SI/SO monitor which can be used to provide an early warning signal to the microprocessor of a potential impending reset signal. The use of the SI/SO monitor allows the microprocessor to finish any signal processing before the reset shuts the microprocessor down. The active Reset circuit operates correctly at an output voltage as low as 1V. The Reset function is activated during the power up sequence or during normal operation if the output voltage drops outside the regulation limits. The reset threshold voltage can be decreased by the connection of an external resistor divider to the RADJ lead.
