DESCRIPTION/ORDERING INFORMATION
The TL1963A is a low-dropout (LDO) regulator optimized for fast transient response. The device can supply 1.5A of output current with a dropout voltage of 340mV. Operating quiescent current is 1mA, dropping to less than 1µA 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 1.21V to 20V. The TL1963A regulators are stable with output capacitors as low as 10µF. 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 1.5V, 1.8V, 2.5V, and 3.3V, 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.
