LA5511,5512
COMPACT DC MOTOR SPEED
CONTROLLER
Application!
■ Ideally suited for speed control of compact DC motor for cassette tape recorder, radio
cassette, 8mm motion-picture camera, record player, etc.
Features
■ Packaged in 4-pin transistor case (equivalent
to T 0 126), thereby enabling easy mounting.
■ Variable reference voltage making it possible to
meet requirements for various types of motor.
■ Excellent stability of each characteristic against
ambient temperature.
• Minimum number of external parts required.
m o n o l it h i c lin e a r IC
■ Low current dissipation (1.0mA max.)
■ Miniflat package

Shunt ratio comes in 2 kinds: k=25 (LA5512)
and k°S0(LA6511). LA5511 |k=50) is small in
loss current OM/k) due to shunt current. Since
motor speed is controlled by varying reference
voltage, loss current (Is) due to speed control
is minimized.
Contains kickback voltage absorber.
