GAPTEC-Electronic GmbH & Co. KG sales@gaptec-electronic.com – www.gaptec-electronic.com Page 1 of 4 LMW78_0.5 – Rev. 2017-1.4 Specifications subject to change without notice. Efficiency up to 95% Ultra wide input voltage range can up to 8:1 Operating temperature: -40°C ~ +85°C Pin-out compatible with LM78XX Linear Short circuit protection (SCP), thermal shutdown Low ripple and noise Micro miniature SIP package, meet UL94-V0 requirement No heatsink required Industry standard pinout MTBF>2,000,000Hours LMW78_0.5 Series The LMW78_0.5 series high efficiency switching regulators are ideally suited to replace LM78xx linear regulators and are pin compatible. It has ultra wide input voltage range, the efficiency of up to 95% means that very little energy is wasted as heat so there is no need for any heatsinks with their additional space and mounting costs.

The load shouldn‘t be less than 10%, and the output external capacitor should not be too large (recommend <10μF), otherwise ripple will increase dramatically. 2. Operation under 10% load will not damage the converter; However, they may not meet all specification listed 3. All specifications measured at Ta=25°C, humidity<75%, nominal input voltage and rated output load unless otherwise specified. 4.

The regulator proposed to establish the input voltage by soft-start, no plug and play, if the input voltage changes from low voltage to high voltage abruptly, the regulator might be damaged. 2. If the applications is high-voltage input, the regulator must add an external capacitor C1(≤47μF/100V),to prevent voltage spikes caused by damage to the module. 3. No parallel connection. Note: 1. The input current amount of the back-grade regulator and the pre-class load should be less than or equal the max load current of the pre-class regulator. 2. If further filtering is required, please add components as per the above circuit (We recommend not to add components), if request, please make sure the capacitors C1 ≤47μF,C2≤10μF more close to the back-grade regulator. High voltage input, multiple outputs, with greater load (figure 3)
