Description

1

-IN

Inverting input

2

+IN

Non-inverting input

3

CC1

Compensation capacitor connection. Select value based on Phase Compensation.

See applicable section.

4

CC2

Compensation capacitor connection. Select value based on Phase Compensation.

See applicable section.

7

OUT

The output voltage sense, no current driving capability; connect this pin to the load

and the feedback resistors.

8, 9

-VS

The negative supply rail. Pins 8 and 9 are internally connected.

10, 11

ILIM

The output with current driving capability. Connect to the current limit resistor.

Output current flows into/out of these pins through RLIM. The output pin and the

load are connected to the other side of RLIM. Pins 10 and 11 are internally con-

nected.

12

TMPL

Cathode side of two parallel-connected temperature-sensing transistors, mounted

on top of one of the sinking and one of the sourcing output elements. Connect to

LTC2997 D- pin for PTAT voltage.

13

TMPH

Anode side of two parallel-connected temperature-sensing transistors, mounted on

top of one of the sinking and one of the sourcing output elements. Connect to

LTC2997 D+ pin for PTAT voltage.

14, 15

+VS

The positive supply rail. Pins 14 and 15 are internally connected.
