DESCRIPTION
1
VIN
Analog I/O
Supply Voltage/LDO Input:
Connect a 1
μ
F capacitor to GND.
2
EN1
Low Voltage Compatible
CMOS Input
LDO-1 Enable.
3
EN2
Low Voltage Compatible
CMOS Input
LDO-2 Enable.
4
CBYP
Analog I/O
Reference Bypass Capacitor Pin:
Optionally connect capacitor of value 0.01
μ
F to 1
μ
F between this pin and GND to tune in the
desired noise and PSRR performance.
5
CPOR
Analog I/O
POR2 Delay Setting Capacitor Pin:
Connect a capacitor between this pin and GND to delay the POR2 output release after LDO-2
output reaches 94% of its specified voltage level. (200ms delay per 0.01
μ
F).
6
GND
Ground
GND is the connection to system ground. Connect to PCB Ground plane.
7
POR1
Open Drain Output (1mA)
Open-drain POR Output for LDO-1 (active-low):
Internally connected to VO1 through 100k
Ω
resistor.
8
POR2
Open Drain Output (1mA)
Open-drain POR Output for LDO-2 (active-low):
Internally connected to VO2 through 100k
Ω
resistor.
9
VO2
Analog I/O
LDO-2 Output:
Connect capacitor of value 1
μ
F to 10
μ
F to GND (1
μ
F recommended).
10
VO1
Analog I/O
LDO-1 Output:
Connect capacitor of value 1
μ
F to 10
μ
F to GND (1
μ
F recommended).
