NJW4116-T1
Io=500mA LDO with Reset function
GENERALDESCRIPTION
The NJW4116 is a 500mAoutput low dropout voltage regulator with reset
function monitoring output voltage.
Reset Output Hold Time is adjustable by external capacitor.
Because of wide operate voltage range and wide temperature range,
the NJW4113 suits for high reliability application such as automotive
application.

RESET Output Delay Hold Time td
The NJW4116 has the RESET Output Delay Hold Time td till the RESET outputs “H” in order to prevent malfunction
due to chattering after the Output Voltage VO exceeds the RESET release voltage VDETH (=VDET+VHYS).
The td is decided by capacitance connected to Cd pin as follows:
External delay capacitor [nF] = (Required) RESET Delay Hold Time td [ms] / 10[ms] x 4.7[nF]
