2.85 TO 12 VOLT FIXED POSITIVE LOCAL VOLTAGE REGULATOR
DEVICE DESCRIPTION
The ZR78L 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 moregeneral voltage regulation applications.
The ZR78L 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
ZR78L devices are completely stable with no external components. The device will shut down under thermal overload conditions but as the device cools, regulation will restart.
