derating-graph (ambient temperature) the r-78bxx-1.5 series high efficiency switching regulators are ideally suited to replace 78xx linear regulators and are pin compatible. the efficiency of up to 95% 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-78b5.0-1.5l en-55022 certified en-55024 certified iec/en-60950-1 certified rohs 2011/65/eu 6/6 refer to application notes specifications (refer to the standard application circuit, ta: 25c, minimum load = 10 %) characteristics conditions min. typ. max. input voltage range all series, see selection guide 4.75v 18.0v output voltage range (for customized parts) all series 1.5v 6.5v output current all series 0ma* 1500ma short circuit input current (vin = 12v) all series 100ma 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) all series 0.3% 0.5% load regulation (10% to 100% full load) all series 0.6% 0.8% dynamic load stability (with output capacitor=100f) 100% <-> 50% load 80mv 120mv transient recovery time 1.0ms 1.5ms ripple & noise (10% to 100% full load) all series 15mv 30mvp-p temperature coefficient -40c ~ +85c ambient 0.015%/c max capacitance load with normal start-up time, no external components 1000f with <1 second start up time + diode protection circuit 6800f switching frequency 300khz 340khz 380khz continued on next page www.recom-power.com i-25 rev: 0/2015
