Negative-input Negative-output Regulator IC
TK721xxCS
1. DESCRIPTION
TK721xxCS series is a negative-input negative-output
regulator IC using silicon monolithic bipolar structure
which can supply 150mA output current.
The output voltage can be set from -2.0 to -9.5V, which is
trimmed in high accuracy.
TK721xxCS is supplied with ON/OFF terminal and noise
reduction terminal. The ON/OFF control can be
controlled directly with positive logic or CPU.
Moreover, TK721xxCS is provided with short-circuit
protection and thermal shutdown.
