ZSR SERIES
2.85 TO 12 VOLT FIXED POSITIVE LOCAL VOLTAGE REGULATOR
DEVICE DESCRIPTION
The ZSR Series three terminal fixed positive voltage
regulators feature internal circuit current limit and
thermal shutdown making the devices difficult to
destroy. The circuit design allows creation of any
custom voltage in the range 2.85 to 12 volts. The
devices are available in a small outline surface mount
package, ideal for applications where space saving is
important, as well as through hole TO92 style
packaging. The devices are suited to local voltage
regulation applications, where problems could be
encountered with distributed single source regulation,
as well as more general voltage regulation
applications.
FEATURES
• 2.85 to 12 Volt
• Output current up to 200mA
• Tight initial tolerance of 2.5%
• Low 600␮a quiescent current
• -55 to 125°C temperature range
• No external components
• Internal thermal shutdown
• Internal short circuit current limit
• Small outline SOT223 package
• TO92 package
The ZSR Series show performance characteristics
superior to other local voltage regulators. The initial
output voltage is maintained to within 2.5% with a
quiescent current of typically 350µA. Output voltage
change, with input voltage and load current, is much
lower than competitive devices. The ZSR devices are
completely stable with no external components.
