RO
LDO Input. Bypass V
IN
to GND with a Ceramic capacitor.
Reset Output. RO remains low while V
is below the reset switching
threshold. RO is in open conector output.
Ground. This pin also functions as a heatsink. Solder to large pads or the
circuit-board ground plane to maximize thermal dissipation.
Reset Delay. RD connects capacitor to GND for setting delay time.
LDO Output. Bypass V
to GND with a minimum 22
μ
F capacitor with
ESR less than 5
at 10kHz.
