MC78PC00 Series Low Noise 150 mA Low Drop Out (LDO) Linear Voltage Regulator The MC78PC00 are a series of CMOS linear voltage regulators with high output voltage accuracy, low supply current, low dropout voltage, MC78PC00 Series MAXIMUM RATINGS Rating Symbol Value Unit Input Voltage V 9.0 V IN Input Voltage V 0.3 ~V +0.3V CE IN Output Voltage V 0.3 ~V +0.3V OUT IN Power Dissipation P 250 mW D Operating Temperature Range T 40 to +85C A Operating Junction Temperature T +125 C J Maximum Junction Temperature T +150 C Jmax Storage Temperature Range T 55 to +125C stg Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied, damage may occur and reliability may be affected.
