NCV4269C LDO Linear Regulator - Micropower, DELAY, Adjustable RESET, Sense Output www.onsemi.com 5.0 V, 150 mA MARKING The NCV4269C is a 5.0 V precision micropower voltage regulator DIAGRAM with an output current capability of 150 mA. The output voltage is accurate within 2.0% with a maximum 8 dropout voltage of 0.5 V at 100 mA. Low quiescent current is a feature SO8 4269C5 drawing only 125 A with a 1.0 mA load. This part is ideal for any and 8 D1 SUFFIX ALYW CASE 751 all battery operated microprocessor equipment. 1 1 Microprocessor control logic includes an active reset output RO with delay and a SI/SO monitor which can be used to provide an early 8 warning signal to the microprocessor of a potential impending reset SO8 signal. The use of the SI/SO monitor allows the microprocessor to 4269C5 EXPOSED PAD 8 finish any signal processing before the reset shuts the microprocessor ALYW PD SUFFIX down. 1 CASE 751AC The active Reset circuit operates correctly at an output voltage as 1 low as 1.0 V. The Reset function is activated during the power up sequence or during normal operation if the output voltage drops 14 outside the regulation limits. SO14 NCV4269C5G The reset threshold voltage can be decreased by the connection of an D2 SUFFIX AWLYWW 14 CASE 751A external resistor divider to the R lead. The regulator is protected ADJ 1 against reverse battery, short circuit, and thermal overload conditions. 1 The device can withstand load dump transients making it suitable for use in automotive environments. The device has also been optimized V426 for EMC conditions.
