COMMON SPECIFICATIONS Item Test Conditions Min. Typ. Max. Units Storage humidity range 95 % Operating temp. range Power derating (above 71 °C) -40 85 Operating case temp. 100 Storage temp. range -55 125 Lead temperature 1.5mm from case for 10 seconds 300 °C Cooling Free Air Convection Case material Plastic (UL94-V0) Storage humidity range 95 % MTBF 25℃(MIL-HDBK-217F) 2000 k hours Package weight 3.7 g FEATURES ● Efficiency up to 96% ●Temperature range: -40°C ~ +85°C ● No heatsink required ● Pin-out compatible with LM78XX linears ● Thermal shutdown ● Low ripple and noise ● SIP package ● Industry standard pinout ● MTBF>2,000,000 hours APPLICATIONS The K78LXX-1000 series high efficiency switching regulators are ideally suited to replace 78xx linear regulators and are pin compatible. The efficiency of up to 96% 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.
