2.85 TO 12 VOLT FIXED POSITIVE LOCAL VOLTAGE REGULATOR ISSUE 5 - JUNE 2006 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 350A. 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. Device Output voltage TO92(C) Package options SOT223(G) ZR78L SERIES FEATURES * * * * * * * * 2.85 to 12 Volt Output current up to 200mA Tight initial tolerance Low quiescent current -55 to 125C temperature range No external components Internal thermal shutdown Internal short circuit current limit SO8(N8) ZR78L028 ZR78L03 ZR78L033 ZR78L04 ZR78L048 ZR78L05 ZR78L052 ZR78L057 ZR78L06 ZR78L07 ZR78L08 ZR78L085 ZR78L09 ZR78L10 ZR78L12 N/A - never available 2.85V 3.0V 3.3V 4.0V 4.85V 5.0V 5.2V 5.7V 6.0V 7.0V 8.0V 8.5V 9.0V 10.0V 12.0V Obsolete Obsolete Obsolete Obsolete Obsolete Obsolete Obsolete Obsolete Obsolete Obsolete Not for new designs Not for new designs Obsolete Obsolete Obsolete Obsolete Not for new designs Not for new designs Obsolete Obsolete Obsolete Obsolete Obsolete Obsolete Obsolete Obsolete Obsolete Obsolete Obsolete Obsolete N/A N/A N/A N/A N/A Obsolete N/A N/A Obsolete N/A N/A N/A N/A N/A N/A The ZSRxxx family of linear regulators are alternatives to the ZR78L family 4-200 ZR78L SERIES ABSOLUTE MAXIMUM RATING Input voltage 20V Output Current(Io) 200mA Operating Temperature -55 to 125C Storage Temperature -65 to 150C Power Dissipation (Tamb=25C) SOT223 2W(Note 3) TO92 600mW S08 780mW(Note 3) ELECTRICAL CHARACTERISTICS: Notes: 1. The maximum operating input voltage and output current of the device will be governed by the maximum power dissipation of the selected package. Maximum package power dissipation is specified at 25 C and must be linearly derated to zero at Tamb=125C. 2. The following data represents pulse test conditions with junction temperatures as indicated at the initiation of the test. Continuous operation of the devices with the stated conditions might exceed the power dissipation limits of the chosen package. 3. Maximum power dissipation, for the SOT223 and SO8 packages, is calculated assuming that the device is mounted on a PCB measuring 2 inches square. 4. The shut down feature of the device operates if its temperature exceeds its design limit as might occur during external faults, short circuits etc. If the regulator is supplied from an inductive source then a large voltage transient, on the regulator input, can result should the shut down circuit operate. It is advised that a capacitor (1F or greater) should be applied across the regulator input to ensure that the maximum voltage rating of the device is not exceeded under shutdown conditions.
