Pin Function
Output voltage of regulator 1 (250mA). Connect externally to pin 16.
Supply input of regulator 1 (highest input voltage required for common circuitry).
Supply input of regulator 2.
Output voltage of regulator 2 (250mA). For fixed output device, connect pins 4
and 5 externally.
Output voltage of regulator 2 (250mA). For fixed output device, connect pins 4
and 5 externally.
Adjust Input. Feedback input for regulator 2.
Enable input to regulator 1. Enables regulator 1 output. Active high input.
High = on, low = off.
Enable input to regulator 2. Enables regulator 2 output. Active high input.
High = on, low = off.
Enable input to regulator 3. Enables regulator 3 output. Active high input.
High = on, low = off.
Reference Bypass: Connect external 0.01µF to GND to reduce output noise.
May be left open.
Ground.
Ground.
Supply input of regulator 3.
Output voltage of regulator 3 (250mA). For fixed output device, connect pins 13
and 14 externally.
Output voltage of regulator 3 (250mA). For fixed output device, connect pins 13
and 14 externally.
Adjust Input. Feedback input for regulator 3.
No Connect. Not internally connected.
Adjust Input. Feedback input for regulator 1.
Output voltage of regulator 1 (250mA). Connect externally to pin 1.
Ground.
