2.85 TO 12 VOLT FIXED POSITIVE LOCAL VOLTAGE REGULATOR ZSR SERIES ISSUE 2 - APRIL 1997 DEVICE DESCRIPTION FEATURES The ZSR Series three terminal fixed positive @ Smaii outline SO8 and SOT223 package voltage regulators feature internal circuit @ TOQ92 package current limit and thermal shutdown making e 2.85 to 12 Volt the devices difficult to destroy. The circuit Output current up to 200MA design allows creation of any custom . urpu _ ent up to voltage in the range 2.85 to 12 volts. The @ Tight initial tolerance devices are available in a small outline @ Low quiescent current surface mount package, ideal for @ -55 to 125C temperature range applications where space saving is @ No external components : o important, as well as through hole TO92 @ Internal thermal shutdown style packaging. The devices are suited to @ Internal short circuit current limit local voltage regulation applications, where problems could be encountered with distributed single source regulation, as weil as more general voltage regulation applications. The ZSR Series show performance characteristics superior to other loca! 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 2SR devices are cornpietely stable with no external components.

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 deratec! to zero at Tamp=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. ZSR SERIES Power Dissipation (Tamb=25C) S0T223 2WiNote 3) TO92 600mW $08 780mW(Note 3) 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 circults etc. Ifthe regulator is supplied from an inductive source then a large voltage transient, on the regulator input, can result should the shut down circuit operate. [t is advised that a capacitor (1uF 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, ZSR285 TEST CONDITIONS (Unless otherwise stated):T;=25C, Ip=100mA, Vj)=6.85V SYMBOL | PARAMETER CONDITIONS MIN.
