DESCRIPTION/ORDERING INFORMATION  
The TL1963A 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 mA 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 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 regulators are stable with output capacitors as low as  
10 mF. 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 regulators are available in the 5-pin  
TO-263 (KTT), 6-pin TO-223 (DCQ), and 3-pin SOT-223 (DCY) packages.
