PIN CONFIGURATION
PIN DESCRIPTION
PIN NO.
PIN NAME
DESCRIPTION
1
POK
This pin will Indicate high under this situation: VO reaches 92% of its rating voltage.
Open-drain output.
2
VEN
The enable control Input pin. As while as this pin’s voltage falls below 0.4V ,the
LR18120 will stop working. When there’s nothing connected with this pin,the device
will be enabled.
3
VIN
The pin of input voltage.
Placing large capacitance closely to this pin is necessary. There should be
connected a 10µF ceramic capacitor.
4
VPP
This pin is for input voltage to control circuit.
5
NC
Connected nothing.
6
VOUT
The voltage output pin.
7
ADJ
When this pin connected to the ground,VOUT will be set by the internal feedback
resistors. Otherwise, if using external feedback resistors to decide the VOUT, VOUT =
0.8(R1+R2)/R2 Volts.
8
GND
Ground.
