derating-graph (ambient temperature) the r-78bxx-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 ver- satile converter series. description * add suffix l for 90 bent pins, e.g. r-78b5.0-1.0l note 1: 1.5v, 1.8v output can be unstable with vin>26vdc
