Pin Symbol Function
1
IN
Input; block to GND directly at the IC with a ceramic capacitor.
2
SI
Sense Input; if not needed connect to OUT
3
PRE
Preregulator Output;
4
D
Reset Delay; to select delay time, connect to GND via capacitor.
5
GND
Ground
6
RO
Reset Output; open-collector output. Keep open, if not needed.
7
SO
Sense Output; open-collector output. Keep open, if not needed.
8
OUT
5-V Output; connect to GND with a capacitor ≥ 4.7μF, ESR < 10 Ω.
1) 2)
1) For the usage of capacitors with very low ESR-values it is recommended to use a small 1Ω resistor in series.
2) Measured at f = 10kHz.
