Lighting levels remain stable to line regulation because of on-chip
voltage reference.
z z
LEDs are driven by a constant current; stable to line regulation.
Power supply
voltage range is wide (3.5 to 16V), for a wide range of applications.
z
Five types of ICs constitute the series with various lighting levels of the LEDs and driving currents.
z
SIP-9 pin package and fewer externally connected components result in smaller space requirements on the circuit board.
z
Low noise at LED lighted mode
