| TA58LT00F TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic TA58LT00F 150 mA Output Current and Tracking Regulator with ON/OFF Control Switch The TA58LT00F consists of small-surface mount type tracking regulators with an output current of 150 mA (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). The output voltage can be controlled to an arbitrary voltage between 2.5V and 13.4V by applying a necessary voltage to ADJ through a microcontroller, etc. It is also possible to enable or disable the regulator via the enable (ON/OFF) terminal. Enabling the regulator only when necessary contributes to the energy saving of equipment.

Note 2: If it is connected EN terminal to IN terminal, be careful so that the negative voltage is not impressed on EN terminal. Note 3: Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the significant change in temperature, etc.) may cause this product to decrease in the reliability significantly even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum ratings and the operating ranges. Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook ("Handling Precautions"/Derating Concept and Methods) and individual reliability data (i.e. reliability test report and estimated failure rate, etc).

Place COUT as close as possible to the output terminal and GND. Although capacitor COUT acts to smooth the dc output voltage during suspension of output oscillation or load change, it might cause output oscillation in a cold environment due to increased capacitor ESR. It is therefore recommended to use a capacitor with small temperature sensitivity. Please connect the resistance of 0.5 2 with the series when the ceramic capacitor is used. 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 * Note that, depending on the load conditions, a steep increase in the input voltage (VIN) may cause a momentary rise in output voltage (VOUT) even if the EN (enable) pin is Low. 5 2006-11-06 TA58LT00F PDmax. - Ta 12 Condition: Number of IC = 1 5.5 VOUT - Tj VIN = 14 V I OUT = 50 mA VEN = 5 V VADJ = 5 V Allowable Power Dissipation PDmax.
