1 / 18 page  2.85 TO 12 VOLT FIXED POSITIVE LOCAL VOLTAGE REGULATOR ISSUE 3 - DECEMBER 2001 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 more general 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 350 µA. 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. FEATURES • Small outline SOT223 package • SO8 package (3.3V and 5.0V) • TO92 package • 2.85 to 12 Volt • Output current up to 200mA • Tight initial tolerance • Low quiescent current • -55 to 125°C temperature range • No external components • Internal thermal shutdown • Internal short circuit current limit VOLTAGE RANGE ZR78L028 2.85V ZR78L03 3.0V ZR78L033 3.3V ZR78L04 4.0V ZR78L048 4.85V ZR78L05 5.0V ZR78L052 5.2V ZR78L057 5.7V ZR78L06 6.0V ZR78L07 7.0V ZR78L08 8.0V ZR78L085 8.5V ZR78L09 9.0V ZR78L10 10.0V ZR78L12 12.0V ZR78L SERIES 4-200 |
