Datasheet
LDO Regulators with Voltage Detector
500 mA Output LDO Regulator
with Voltage Detector
BD42754FP2-C
General Description
BD42754FP2-C, BD42754FPJ-C are automotive suited
voltage regulator with 1ch Reset and offers the output
current of 500mA while limiting the low quiescent
current.
These regulators are therefore ideal for applications
requiring a direct connection to the battery and a low
current consumption. A reset signal is generated for an
output voltage VO of Typ 4.62 V.
The reset delay time can be programmed by the external
capacitor.
Features
Low ESR ceramic capacitors applicable for output.
Low drop voltage: PDMOS output transistor
Power on and under-voltage reset
Programmable reset delay time by external capacitor.
Applications
Onboard vehicle device
(Engine ECU, Body-control car stereos, satellite
navigation system, etc.)
