TA58MS033, 05, 06, 08, 09, 12F TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic TA58MS033F,TA58MS05F, TA58MS06F, TA58MS08F,TA58MS09F, TA58MS12F 500-mA Low Dropout Voltage Regulators with ON/OFF Control Switch The TA58MS**F are small surface-mount low-dropout voltage regulators that provide up to 500mA of output current and an on/off control switch. The EN input can be used to turn on and off the device as necessary and thus helps save system power. The TA58MS**F are suitable for applications requiring low power consumption due to low-dropout voltage and low standby current. Features Active-High on/off switch Up to 500-mA output current HSIP5-P-1.27B Output voltages: 3.3 / 5 / 6 / 8 / 9 / 12 V Weight : 0.36 g (Typ.) Output voltage accuracy : V 3% ( T = 25C) OUT j Low quiescent current: 2.5 mA typ. ( I = 0 A) OUT Low standby current (output OFF mode): 1.0A (max) Low-dropout voltage: 0.7 V (max) ( I = 500 mA) except the TA58MS033F OUT Overcurrent protection / thermal shutdown / 60V load dump protection / overvoltage protection Package: 5-pin New PW-Mold (surface-mount) Pin Assignment Marking 3 Part No. (or abbreviation code) 1 IN 58MS** Note 2 2 EN F 3 GND Lot No. 4 NC 5 OUT Note 1 1 3 2 4 5 Note 1: A line under a Lot No. identifies the indication of product Labels.
