LDO Regulators with Voltage Detector
200mA / 300mA Output LDO Regulator
with 2ch RESET
BD4269FJ-C BD4269EFJ-C
General Description
BD4269FJ-C BD4269EFJ-C are a low quiescent
voltage regulator with 45V absolute maximum voltage
allowing usage in battery direct-connected systems. IC
integrates Power on and under-voltage reset and Input
voltage reset for VCC or other voltages. Quiescent
current is minimized to optimize the system current
consumption. Offers selection of the output current
between 200 mA or 300 mA depending on the
application.
Power on and under-voltage reset and Input voltage
reset threshold voltage can be adjusted by external
resistance. Power on and under-voltage reset delay time
can programmed set by external capacitor.
Features
AEC-Q100 Qualifies (Note 1)
Low ESR ceramic capacitors applicable for output.
Low drop voltage: PDMOS output transistor
Power on and under-voltage reset
Sense input comparator for VCC or other voltage
Adjustable power on and under-voltage reset and
Sense input comparator by external resistance
Programmable reset delay time by external capacitor.
