TP78Lxx-1.5
Series  
DESCRIPTION  
：
Wide Input Non-Isolated & Regulated Single Output  
TP78LXX-1.5 series switching regulators are ideal replacement for TP78xx linear regulators  
and LDOs. 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. They are  
widely used in industrial control, instrumentation, and electric power applications.  
FEATURES

STANDARD APPLICATION CIRCUIT  
TP78LXX-1.5  
Note:  
1. C1 and C2 are required and should be fitted close to the converter pins.  
2. The capacitance of C1,C2 sees external capacitor table, it can be increased properly if required, anntaum or low ESR electrolytic capacitors may also suffice.  
3. No parallel connection or plug and play.
