OUTPUT VOLTAGE ADJUSTMENT (for 5V output variants)
The trimming (adjust) input on the device allows output voltage adjustment from 1.2V to 3.3VDC by using a resistor as shown here. The table below provides RTRIM values for the
most commonly required output voltages. For applications not requiring the TRIM function, this pin must be left unconnected for normal regulated output.

RoHS COMPLIANCE INFORMATION
This series is compatible with RoHS soldering
systems with a peak wave solder temperature of
300ºC for 10 seconds. The pin termination finish
on the SIP package type is Tin Plate, Hot Dipped
over Matte Tin over Nickel Preplate. The DIP
types are Matte Tin over Nickel Preplate. Both
types in this series are backward compatible
with Sn/Pb soldering systems.
