DESCRIPTION/ORDERING INFORMATION

The TL1963A-xx is a low-dropout (LDO) regulator optimized for fast transient response. The device can supply

1.5 A of output current with a dropout voltage of 340 mV. Operating quiescent current is 1 mA, dropping to less

than 1 μA in shutdown. Quiescent current is well controlled; it does not rise in dropout as it does with many other

regulators. In addition to fast transient response, the TL1963A-xx regulators have very low output noise, which

makes them ideal for sensitive RF supply applications.

Output voltage range is from 1.21 V to 20 V. The TL1963A-xx regulators are stable with output capacitors as low

as 10 μF. Small ceramic capacitors can be used without the necessary addition of ESR, as is common with other

regulators. Internal protection circuitry includes reverse-battery protection, current limiting, thermal limiting, and

reverse-current protection. The devices are available in fixed output voltages of 1.5 V, 1.8 V, 2.5 V, and 3.3 V,

and as an adjustable device with a 1.21-V reference voltage. The TL1963A-xx regulators are available in the

5-pin TO-263 (KTT), 6-pin SOT-223 (DCQ), and 3-pin SOT-223 (DCY) packages.

Adjustable Operation The adjustable device is tested and specified with the ADJ pin tied to the OUT pin for an output voltage of 1.21 V. Specifications for output voltages greater than 1.21 V are proportional to the ratio of the desired output voltage to 1.21 V: VOUT/1.21 V.

TL1963A-xx SLVS719F – JUNE 2008 – REVISED MAY 2011 www.ti.com The problem occurs with a heavy output load when the input voltage is high and the output voltage is low. Common situations are immediately after the removal of a short circuit or when the shutdown pin is pulled high after the input voltage has already been turned on. The load line for such a load may intersect the output current curve at two points. If this happens, there are two stable output operating points for the regulator.

TL1963A-xx www.ti.com SLVS719F – JUNE 2008 – REVISED MAY 2011 Calculating Junction Temperature Example: Given an output voltage of 3.3 V, an input voltage range of 4 V to 6 V, an output current range of 0 mA to 500 mA, and a maximum ambient temperature of 50°C, what is the maximum junction temperature? The power dissipated by the device is equal to: IOUT(MAX)(VIN(MAX) – VOUT) + IGND(VIN(MAX)) where, IOUT(MAX) = 500 mA VIN(MAX) = 6 V IGND at (IOUT = 500 mA, VIN = 6 V) = 10 mA So, P = 500 mA (6 V – 3.

TL1963A-xx SLVS719F – JUNE 2008 – REVISED MAY 2011 www.ti.com When the IN pin of the TL1963A-xx is forced below the OUT pin or the OUT pin is pulled above the IN pin, input current typically drops to less than 2 μA. This can happen if the input of the device is connected to a discharged (low voltage) battery and the output is held up by either a backup battery or a second regulator circuit. The state of the SHDN pin has no effect on the reverse output current when the output is pulled above the input.
