NJM78LR05 SERIES REGULATOR WITH RESET FUNCTION GENERAL DESCRIPTION PACKAGE OUTLINE The NJM78LR05 is a series regulator with reset function. In case of shut down or output voltage drop, the IC generates reset signal to a microcomputer. That is suitable for items with microcomputer, such NJM78LR05BD / CD NJM78LR05BM / CM / DM as TV sets, remote controller, refrigerator and others. FEATURES Output Current I =150mA max. O Reset Function Including Reset Delay Time can be Adjusted NJM78LR05BL / CL NJM78LR05BU / CU / DU by an External Capacitance. Internal Over Current Protection Thermal Shut Down Bipolar Technology package Outline DIP8, DMP8, SIP8, SOT-89 (5Pin) RESET THRESHOLD VOLTAGE LINE-UP Reset Threshold Voltage Version Part Number 4.0V D NJM78LR05DX 4.2V C NJM78LR05CX 4.3V B NJM78LR05BX X is package suffix.
