The RH137 negative adjustable regulator will deliver up to 1.5A output current over an output voltage range of –1.2V to –22V. Every effort has been made to make these devices easy to use and difficult to damage. Internal current and power limiting coupled with true thermal limiting prevents device damage due to overloads or shorts, even if the regulator is not fastened to a heat sink. Maximum reliability is attained with Linear Technology’s advanced processing techniques combined with a 100% burn-in in the thermal limit mode. This assures that all device protection circuits are working and eliminates field failures experienced with other regulators that receive only standard electrical testing. The wafer lots are processed to Linear Technology’s inhouse Class S flow to yield circuits usable in stringent military applications.
