LNBH23L Pin configuration
Doc ID 15335 Rev 4 9/25
Pin n° Symbol Name Pin function
Epad Epad Exposed pad
To be connected with power grounds and to the ground layer
through vias to dissipate the heat.
20 A-GND Analog ground Analog circuits ground.
15 BYP By-pass capacitor
Needed for internal pre-regulator filtering. The BYP pin is
intended only to connect an external ceramic capacitor. Any
connection of this pin to external current or voltage sources
may cause permanent damage to the device.
10 ADDR Address setting
Two I²C bus addresses available by setting the Address pin
level voltage. See address pin characteristics table.
28 ISEL Current selection
The resistor “RSEL” connected between ISEL and GND defines
the linear regulator current limit threshold by the equation:
I
MAX
(typ.) = 10000 / RSEL.
30 Reserved Reserved To be left floating. Do not connect to GND.
1, 2, 3, 7, 8,
16, 17, 23,

31, 32
N.C.
Not internally
connected
Not internally connected pins. These pins can be connected to
GND to improve thermal performances.
