TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic
TA58LT00F
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.

Electrical Characteristics Common to All Products
• Tj = 25°C in the measurement conditions of each item is a regulation for where the standard condition
when a pulse test is carried out, and any drift in the electrical characteristic due to a rise in the junction
temperature of the chip may be disregarded.

Load
• Place CIN as close as possible to the input terminal and GND. 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∼ 2Ω 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.
