INFORMATION
FEATURES
■ Regulated Output to 2 %
■ 5 mA Output Current
■ Operating Range 1.8 to 8 V
■ Enable Pin
■ Miniature Package (SOT-23L-6)
■ Standby Current (2 µA)
DESCRIPTION
The TK65018 is a monolithic switched capacitor converter
with regulation. With just two capacitors, the TK65018 can
create a negative voltage supply with regulation.
With no external timing elements, the converter will selfoscillate at 166 kHz, nominal.

Quiescent current is typically 50 µA. Standby current is
guaranteed less than 2 µA over the full operating
temperature and input voltage ranges.
The TK65018 is available in miniature SOT-23L-6 surface
mount package. Customized levels of output voltages are
available. The TK65018 is available with the following
output voltages: -5.0 V, -4.1 V, -3.5 V, -3.0 V, -2.1 V, -1.5,
-0.5 V.
