R-78C-1.0

Description

The R-78Cxx-1.0 series switching regulators are ideally suited to replace 1 Amp 78xx linear regulators

and are pin compatible. Efficiencies of up to 96% means that very little energy is wasted as heat and

the high input voltage is a useful feature.

Notes:

Note1: No load operation will not damage these devices, however they may not meet all specifications

A minimum load of 10mA is required

Note2: Measurements are made with a 10µF MLCC across output. (low ESR)
