Pin Symbol Function
1I
Input.
IC supply. For compensating line influences, a capacitor of 220 nF close to the IC pins is
recommended.
2 N.C
Not Connected.
3 GND
Ground Reference.
Connect this pin low ohmic to GND.
4 EN
Enable.
A low signal disables the IC. A high signal switches it on.
Connect to the input I, if the enable functionality is not required.
5 RO
Reset Output
The open collector output can be connected to a microcontroller using a external pull up resistor.
If the functionality is not required, the pin can be left open.
6 RADJ Reset Adjust.
For reset threshold adjustment connect to a voltage divider from output Q to GND.
(“Description Reset Function” on Page 20)
7 ADJ
FB
Adjust. (Only Adjustable Version TLS208D1EJV)
The reference voltage can be connected to the output pin directly or by a voltage divider for
higher output voltages (see application information).
Feedback. (Only Fixed Voltage Versions e.g. TLS208D1EJV33)
The Feedback pin has to be connected to the output voltage.
8Q
Output.
Block to GND with a capacitor close to the IC terminals, respecting capacitance and ESR
requirements given in the table “Functional Range” on Page 8.
Pad EP
Exposed Pad.
Connect to PCB heat sink area and GND.

1) Referring to the device tolerance only, the tolerance of the resistor divider can cause additional deviation. Parameter is
tested with ADJ-Pin directly connected to the output Q.
2) This parameter is not subject to production test, specified by design
3) The input voltage condition is intended to ensure that the device is out of the drop condition.
4) Tested with ADJ-Pin directly connected to the output Q.
5) Dropout voltage is defined as the difference between input and output voltage when the output voltage decreases 100 mV
from output voltage measured at VI = VQ,nom + Vdr,max + 100 mV.
6) The dropout voltage might be limited to the minimum input voltage as defined in P_4.2.1 on Page 8
7) ADJ pin pull up current flows out of the ADJ pin.
