General Description

BD4275FP2-C and BD4275FPJ-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 (body-control, car stereos,

satellite navigation system, etc)
