(TA78DM05S - TA78DM12S) LOW DROPOUT VOLTAGE REGULATOR
Description
TA78DM05,08,09,12S
TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic
TA78DM05S, TA78DM08S, TA78DM09S, TA78DM12S
5 V, 8 V, 9 V, 12 V Three-Terminal Low Dropout Voltage Regulator
The TA78DM××S series consists of fixed-positive-output voltage regulator ICs capable of sourcing current of up to 500 mA.
Due to the features of low dropout voltage and low standby current, these devices are useful for battery-powered equipment.
Features
Low standby current of 800 µA typical.
Maximum output current of 500 mA.
Low dropout voltage: 0.
75 V (max).
Weight: 1.
7 g (typ.
) Multi-protection: Reverse connection of power supply, 60 V load dump, thermal shut down and current limiting.
Metal fin (tab) is fully covered with mold resin.
