Shutdown control input for V
OUT1
. Regulator 1 is fully enabled when a logic high is applied to
this input. Regulator 1 enters shutdown when a logic low is applied to this input. During
shutdown, regulator output voltage falls to zero, RESET output remains valid.
Shutdown control input for V
OUT2
. Regulator 2 is fully enabled when a logic high is applied to
this input. Regulator 2 enters shutdown when a logic low is applied to this input. During
shutdown, regulator output voltage falls to zero, RESET output remains valid.
Reference bypass input. Connecting a 0.01
μ
F to this input further reduces output noise.
Regulated voltage output 1.
Regulated voltage output 2.
RESET Output. RESET = Low when V
DET
is below the Reset Threshold Voltage.
RESET = High when V
DET
is above the Reset Threshold Voltage.
