EN1, EN2

Both enable inputs are active high, requiring 1.0V for

guaranteed logic HIGH level detection (VIH =1.0V

MIN). EN1 provides logic control of both the DC/DC

regulator and LDO1. EN2 provides logic control for

LDO2 only. The enable inputs are CMOS logic and

cannot be left floating.

The enable pins provide logic level control of the

specified outputs. When both enable pins are in the

OFF state, supply current of the device is greatly

reduced (typically < 1 µA). When the DC/DC regulator

is in the OFF state, the output drive is placed in a

“tri-stated” condition, where both the high side

P-channel MOSFET and the low-side N-channel are in

an OFF or nonconducting state. Do not drive either of

the enable pins above the supply voltage.
