TA48LS015, 018, 025, 033, 05F TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic TA48LS015F, TA48LS018F, TA48LS025F, TA48LS033F, TA48LS05F 300 mA Output Current and Low Dropout Voltage Regulator with ON/OFF Control Switch The TA48LS***F series consists of small-surface mount type low-dropout regulators with an output current of 300mA (maximum) and an ON/OFF control switch. Control by an EN (ON/OFF) terminal enables the regulator to be operated only when required (output ON). Therefore these newly developed regulators are suitable for use in the power supply circuits of AV, OA and other digital devices equipped with a stand-by function, and of battery-operated portable data devices of various types, where they will contribute to energy saving. Moreover, the regulators have an output voltage line-up starting from 1.5V, corresponding to the lower voltage of various devices. Weight : 0.08 g (Typ.)

Standard Application Circuit CIN 0.33 μF IN OUT TA48LS***F EN CPU etc. COUT 1 μF NC GND Load • Be sure to connect a capacitor near the input terminal and output terminal between both terminals and GND. The use of a monolithic ceramic capacitor (B Characteristic or X7R) of low ESR (equivalent series resistance) is recommended. The IC may oscillate due to external conditions (output current, temperature, or the type of the capacitor used). The type of capacitor required must be determined by the actual application circuit in which the IC is used. The notice in case of application • The IC might be destroyed if a voltage greater than the input terminal voltage is applied to the output terminal, or if the input terminal is connected to GND during operation. To prevent such an occurrence, connect a diode as in the following diagram. CIN 0.33 μF CPU etc. IN OUT TA48LS***F EN NC GND COUT 1 μF Load • There is a possibility that internal parasitic devices may be generated when momentary transients cause a terminal’s potential to fall below that of the GND terminal. In such case, that the device could be destroyed. The voltage of each terminal and any state must therefore never fall below the GND potential. • Depending on the load conditions, a steep increase in the input voltage applied (VIN) may cause a momentary rise in output voltage (VOUT) even if the EN (enable) pin is Low.
