Function
Voltage Adjust. A resistor divider from V OUT to this lead sets the output voltage.
± 2.0%, 400 mA output.
No connection.
Input Voltage.
Monitor. Input to comparator. If not needed connect to V OUT.
Reset adjust. If not needed connect to ground.
Timing capacitor for RESET function.
Ground. All GND leads must be connected to Ground .
ENABLE control for the IC. A high powers the device up.
Active reset (accurate to V OUT ≥ 1.0 V)
Open collector output from comparator.
NOTE:
Tentative pinout for SOW ? 16 E Pad.
