Description for the TL1963A
The TL1963A-xx regulators are low-dropout (LDO) regulators provides a robust, easy-to-use power management design for wide variety of applications. The device can supply 1.5A of output current with a dropout voltage of 340mV (typical) and supports wide output range (from 1.21V to 20V) in adjustable configuration. In addition, TL1963A-xx also supports tighter output accuracy ±1.5% across line, load and temperature (for DCQ, KTT package of new chip), fast transient response, and low output noise (23µVRMS in unity-gain adjustable configuration), making it an excellent choice for sensitive RF supply applications.
The TL1963A-xx regulators are stable with output capacitor as low as 10µF and supports ESR range up-to 3Ω. The TL1963A-xx (both legacy chip and new chip) has built-in protection mechanism for over-current, over-temperature (thermal shutdown) and reverse-current protection for reliable operation of the LDO and the legacy chip of TL1963A-xx also includes reverse-battery protection.
The TL1963A-xx is available in a 6.50mm × 7.0mm, 4-pin SOT-223 (DCY) [only fixed], 6.50mm × 7.06mm, 6-pin SOT-223 (DCQ) and 10.16mm × 15.24mm, 5-pin DDPAK/TO-263 (KTT) package for fixed and adjustable outputs.
