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.
