PIN DESCRIPTIONS
The descriptions of the pins are listed in Table 3-1.
TABLE 3-1:
Pin Description Table.
3.1
Voltage Detect Input (V
DET
)
Input pin that is compared to internal threshold voltage
(typically 2.63V). When the V
DET
input is below the
2.63V threshold, the RESET output is held in its normal
low state. When the input voltage on the V
DET
pin rises
above the threshold voltage, the RESET output pin
remains low for 300 mS (Typical). After the delay, the
RESET pin changes to a logic high state.
3.2
Shutdown Control Input for V
OUT1
(SHDN1)
LDO#1 output is enabled when a logic high is applied
to the SHDN1 input. LDO#1 output is disabled with a
logic low tied to the SHDN1 pin. When shutdown,
LDO#1 enters a low quiescent current state and the lin-
ear pass P-Channel MOSFET is off. The RESET out-
put remains valid and is independent of SHDN1.
3.3
SELECT Control Input for Setting
V
OUT1
and V
OUT2
(SELECT12)
Input pin used to select the output voltage of LDO#1
and LDO#2. When SELECT is tied to V
IN
, V
OUT1
=
V
OUT2
= 3.0V. When SELECT is tied to GND, V
OUT1
=
V
OUT2
= 2.5V. If the SELECT input is not connected,
V
OUT1
= V
OUT2
= 2.8V.
3.4
Input Voltage V
IN
Connect input source to this pin. All V
IN
pins must be
tied together.
3.5
Ground (GND)
Connect this pin to the circuit ground. NOTE: This pin
does not carry high current and should be connected to
quiet circuit ground.
3.6
Shutdown Control Input for V
OUT3
(SHDN3)
LDO#3 output is enabled when a logic high is applied
to the SHDN3 input. LDO#3 output is disabled with a
logic low tied to the SHDN3 pin. When shutdown,
LDO#3 enters a low quiescent current state and the lin-
ear pass P-Channel MOSFET is off. The RESET out-
put remains valid and is independent of SHDN3.
3.7
Shutdown Control Input for V
OUT4
(SHDN4)
LDO#4 output is enabled when a logic high is applied
to the SHDN4 input. LDO#4 output is disabled with a
logic low tied to the SHDN4 pin. When shutdown,
LDO#4 enters a low quiescent current state and the lin-
ear pass P-Channel MOSFET is off. The RESET out-
put remains valid and is independent of SHDN4.
3.8
SELECT Control Input for Setting
V
OUT3
and V
OUT4
(SELECT34)
Input pin used to select the output voltage of LDO#3
and LDO#4. When SELECT is tied to V
IN
, V
OUT3
=
V
OUT4
= 2.8V. When SELECT is tied to GND, V
OUT3
=
V
OUT4
= 1.8V. If the SELECT input is not connected,
V
OUT3
= V
OUT4
= 2.5V.
3.9
Regulated Output Voltage #4 (V
OUT4
)
Output voltage selected by tri-state input SELECT34.
Output can be set to 1.80V, 2.50V or 2.80V
3.10
Regulated Output Voltage #3 (V
OUT3
)
Output voltage selected by tri-state input SELECT34.
Output can be set to 1.80V, 2.50V or 2.80V
3.11
Regulated Output Voltage #2 (V
OUT2
)
Output voltage selected by tri-state input SELECT12.
Output can be set to 2.50V, 2.80V or 3.00V
3.12
Regulated Output Voltage #1 (V
OUT1
)
Output voltage selected by tri-state input SELECT12.
Output can be set to 2.50V, 2.80V or 3.00V.
