Description
Regulator output.
Current error amplifier input (current sense at higher voltage)
Current error amplifier input (current sense at lower voltage)
E/A output for frequency compensation.
Feedback input. Connecting directly to this pin results in an output voltage of
1.23 V. An extenal resistive divider is required for higher output voltages.
3.3 V reference voltage. No cap is need for stability.
Ground.
Unregulated DC input voltage.
