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, a s w e l l a s m ore ge ner a l vol t age r e g u l a t i o n applications. 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 petitive devices. The ZSR devices are pletely stable with no external ponents.
