" derating-graph (ambient temperature) the r-78bxx-1.0 series high efficiency switching regulators are ideally suited to replace 78xx linear regulators and are pin compatible. the efficiency of up to 97% means that very little energy is wasted as heat so there is no need for any heat sinks with their additional space and mounting costs. the l-version with 90 pins allows direct replacement for laid-flat regulators where component height is at a premium. low ripple and noise figures and a short circuit input current of typically only 10ma round off the specifications of this versatile converter series. description * add suffix ?l? for 90 bent pins, e.g. r-78b5.0-1.0l en-55022 certified en-55024 certified en-6060 1-1-2 certified iec/en-60950-1 certified rohs 2011/65/eu 6/6 refer to application notes characteristics conditions min. typ. max. input voltage range 1.5v, 1.8v 4.75v 25 26v abs. max. 2.5v to 15.5v 4.75v 32 34v abs. max. output voltage range (for customized parts) all series 1.5v 15.5v output current (see note 1) all series 0ma* 1000ma short circuit input current (vin = 24v) all series 60ma internal power dissipation 0.65w short circuit protection continuous, automatic recovery output voltage accuracy (at 100% load) all series 2% 3% line voltage regulation (vin = min. to max. at full load) 1.5v to 6.5v 0.2% 0.4% 9v to 15.5v 0.1% 0.2% load regulation (10% to 100% full load) 1.5v to 6.5v 0.4% 0.6% 9v to 15.5v 0.25% 0.4% dynamic load stability (with output capacitor=100f) 100% <-> 50% load 100mv 150mv transient recovery time 1.0ms 1.5ms ripple & noise (without output capacitor) 1.5v to 6.5v 15mvp-p 20mvp-p (10% to 100% full load) 9v to 15.5v 25mvp-p 35mvp-p temperature coefficient -40c ~ +85c ambient 0.015%/c continued on next page specifications (refer to the standard application circuit, ta: 25c, minimum load = 10%) www.recom-power.com i-21 rev: 0/2015 8!!* *3 8!!* *3-1 - &226, -9$ - -9$- -9- -9#$#- - - # -9$- -9- -9- -9:- -9$- efficiency 72 - 72 -1 - &226, -9$-;$ - -9$- -9- -9#$#- - - # -9:-;- -9- -9$- ripple r-78b-1.0 characteristics conditions min. typ. max. max capacitance load with normal start-up time, no external components 470f with <1 second start up time + diode protection circuit 6800f switching frequency 280khz 330khz 380khz quiescent current vin = min. to max. at 0% load 5ma 7ma input reflected ripple current all series 150ma 200map-p operating temperature range -40c +85c operating case temperature +100c storage temperature range -55c +125c case thermal impedance 60c / w relative humidity 95% rh case material epoxy with non-conductive plastic case (ul94v-0) package weight 4g packing quantity 42 pcs per tube conducted emissions en55022 class b radiated emissions en55022 class b esd en61000-4-2 class a iec/en general safety report: spclvd 1407030-1 iec/en-60950-1, 2nd edition mtbf (+25c) using mil-hdbk 217f 6584 x 103 hours .
