DETAILED PIN DESCRIPTION

Name

Description

Enable

The enable pin allows the user to control the output. A low signal disables the output and places

the device into a low current standby mode.

GND

Ground pin.

N/C

This pin is not connected to the device.

Vout

Regulated output voltage.

Vin

Input voltage.

Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit

values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied,

damage may occur and reliability may be affected.

ELECTRICAL CHARACTERISTICS (TA = 25°C, for min/max values TA is the operating junction temperature that

applies, VCC = 3.5 V, unless otherwise noted)
