Description

1

OUT

Regulator output.

2

CS+

Current error amplifier input (current sense at higher voltage)

3

CS-

Current error amplifier input (current sense at lower voltage)

4

COMP

E/A output for frequency compensation.

5FB

Feedback input. Connecting directly to this pin results in an output

voltage of 1.23V. An extenal resistive divider is required for higher output

voltages.

3.3V reference voltage. No cap is need for stability.

7

GND

Ground.

8

VCC

Unregulated DC input voltage.
