Samsung KA2402 Datasheet
KA2402 DC MOTOR SPEED CONTROLL ER
INTRODUCTION
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.
• V
= 0.2V
