SAMSUNG KA2402

KA2402
DC MOTOR SPEED CONTROLLER
INTRODUCTION
8-DIP-300
USE
• Speed control or general-purpose low-voltage compact DC
motor for microcassette tape recorders, radio cassettes and
their equivalents.
FEATURES
• Operating supply voltage range
KA2402: Vcc=1.8V ~ 8V
• Capable ot making the applicable set compact because of a
minimum of adjust speed.
• Easy to adjust speed.
• Built-in stable low reference power meeting the requirements for
2 speeds.
• VREF = 0.2V
