Features
1) With 9V output for audio power supply, 5V output for
microcontrollers, 5V output for radio, 5 and 7.5V out-
puts for CD players, 9.5V output for motor drivers, the
IC is best suited for CD radio cassette players.
2) Precise power supply (5V
±
0.1V) can be obtained by
using external reference voltage input (only AUDIO
output has an internal reference voltage system).
3) Zero standby current. (Type.)
4) Output current limit circuit protects the IC against
short-circuiting damage.
5) Compact SIP-M12 package allows a large power dis-
sipation (3W : no heat sink).
6) Thermal protection circuit prevents heat damage to
the IC.
