TS39100/1/2/3

1.0A Ultra Low Dropout Positive Voltage Regulator

Low Dropout Voltage 0.4V (typ.)

Enable Input Control

Adjustable Output

Error Flag Detection

General Description

The TS39100/1/2/3 series are 1A ultra low dropout linear voltage regulators that provide low voltage, high current output

from an extremely small package. These regulator offers extremely low dropout (typically 400mV at 1A) and very low

ground current (typically 12mA at 1A).

The TS39100/1/2/3 series are fully protected against over current faults, reversed input polarity, reversed lead insertion,

over temperature operation, positive and negative transient voltage spikes, logic level enable control and error flag which

signals whenever the output falls out of regulation.

On the TS39101/2/3, the enable pin may be tied to Vin if it is not required for enable control. This series are offered in

3-pin SOT-223 (TS39100), 8-pin SOP (TS39101/2) and 5-pin TO-252 (TS39103) package.

Note 1: Absolute Maximum Rating is limits beyond which damage to the device may occur. For guaranteed

specifications and test conditions see the Electrical Characteristics.

Note 2: The device is not guaranteed to operate outside its operating rating.

Note 3: Devices are ESD sensitive. Handling precautions recommended.

Note 4: The maximum allowable power dissipation is a function of the maximum junction temperature, Tj, the junction to

ambient thermal resistance, ja, and the ambient temperature, Ta. Exceeding the maximum allowable power

dissipation will cause excessive die temperature, and the regulator will go into thermal shutdown. The effective

value of ja can be reduced by using a heatsink, Pd

Note 5: Dropout voltage is defined as the input to output differential at which the output voltage drops -1% below its

nominal value measured at 1V differential.

Note 6: Ground pin current is the regulator quiescent current. The total current drawn from the source is the sum of the

ground pin current and output load current, Iin = Ignd + Iout.

Note 7: Vref ≤ Vout ≤ (Vin – 1V), 2.25V ≤ Vin ≤ 16V, 10mA ≤ I
