ZSR SERIES 3.0 to 12 volt fixed positive local voltage regulator Description Features The ZSR Series three terminal fixed positive voltage regulators feature internal circuit current limit and thermal shutdown making the devices difficult to destroy. The devices are available in a high power surface mount package, ideal for applications where space saving is important. 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. • Output current up to 200mA • Tight initial tolerance of 2.5% • Low 600A quiescent current • -55 to 125°C temperature range • No external components • Internal thermal shutdown • Internal short circuit current limit • High power SOT223 package 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 350A. Output voltage change, with input voltage and load current, is much lower than competitive devices. The ZSR devices are completely stable with no external components.

Maximum package power dissipation is specified at 25°C and must be linearly derated to zero at Tamb=125°C. • 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. Issue 9 - October 2007 © Zetex Semiconductors plc 2007 • 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. 2 www.zetex.com ZSR SERIES Electrical characteristics ZSR300 test conditions (Unless otherwise stated):Tj=25°C, IO=100mA, Vin=7V Symbol VO Parameter Output Voltage Conditions IO=1 to 200mA() Min. 2.92 2.88 Vin=5 to 20V 2.88 Typ. 3.0 Max. 3.08 3.12 Units V V 3.12 V IO =1 to 100mA() ⌬VO Line regulation Vin=5 to 20V 10 40 mV ⌬VO Load regulation IO=1 to 200mA 5 25 mV 2 Ig Quiescent current IO=1 () ⌬Ig Quiescent current change IO=1 to 200mA Vin=1 to 20V to 100mA 350 Vn Output noise voltage f=10Hz to 10Hz ⌬Vin/⌬VO Ripple rejection Vin=1 to 20V Vin Input voltage required to maintain regulation Average temperature coefficient of VO 48 mV 600 A 100 A 100 A 75 V rms 62 dB 4.7 V 0.1 mV/°C f=120Hz ⌬VO/⌬T IO=5.0mA() ZSR330 test conditions (Unless otherwise stated):Tj=25°C, IO=100mA, Vin=7.3V Symbol VO Parameter Output Voltage Conditions IO=1 to 200mA() Min. 3.218 3.168 Vin=5.3 to 20V 3.168 IO =1 to Typ. 3.3 Max. 3.382 3.432 Units V V 3.432 V 100mA() ⌬VO Line regulation Vin=5.3 to 20V 7.5 30 mV ⌬VO Load regulation IO=1 to 200mA 5 25 mV IO=1 to 100mA 2 Ig Quiescent current () ⌬Ig Quiescent current change IO=1 to 200mA 100 A Vin=5.3 to 20V 100 A 350 Vn Output noise voltage f=10Hz to 10Hz ⌬Vin/⌬VO Ripple rejection Vin=6.3 to 18V 50 mV 600 A 50 V rms 64 dB 5 V f=120Hz Vin ⌬VO/⌬T NOTES: ()Tj=-55 Input voltage required to maintain regulation Average temperature coefficient of VO IO=5.0mA() 0.1 mV/°C to 125°C Issue 9 -
