( October 22, 2003 ) – Catalyst Semiconductor,
Inc. (NASDAQ:CATS), has added shunt voltage regulators to its mixed
signal product line. The CAT431L is a precision 1.24 volt shunt
regulator featuring 0.5 percent accuracy. The CAT102 is a precision
0.6 volt shunt regulator. Output voltage for both regulators can
be set with external resistors.
"Shunt voltage regulators will sell along
side our digital potentiometers in high end power supplies that
target non-consumer computer and telecommunication systems. Additional
products scheduled for later this year will integrate regulators
with microcontroller supervisory functions," said Catalyst
Semiconductor Director of Marketing David Gillooly.
CAT431L Features
The CAT431L offers twice the accuracy of the pin compatible TLV431A
device. Initial output voltage reference accuracy is ±0.5
percent or ± 6 millivolts. Surface mount and through-hole
PCBs are supported with SOT23 packages and the 3-lead, TO-92 package.
CAT102 Features
The 0.6V output voltage of the CAT102 makes it ideal for low voltage
power supplies. Initial output accuracy is ±1% or 6 millivolts.
Power supply rejection is 45 dB at 300 kilohertz. The error amplifier
power supply connection and the output are available on separate
pins.
Price, Packages and Availability
The CAT431L is offered in SOT-23 and TO-92 packages. It
is a higher precision, drop-in replacement for the Texas Instruments
TLV431A. The CAT102 is available in a SOT23 package. Prices start
at $0.14 in 10,000 piece quantities. Devices are currently available
for sampling and production orders.
