1.5-A, 20-V, low-dropout voltage regulator with reverse current & reverse voltage protection

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.
