Product Overview

The TL1963A-33DCYR is a 1.5A low-noise fast-transient-response 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 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.
  • 40µVRMS Low noise
  • 1mA Quiescent current
  • No protection diodes needed
  • Controlled quiescent current in dropout
  • Less than 1µA Quiescent current in shutdown
  • Stable with 10µF ceramic output capacitor
  • Reverse-battery protection
  • Reverse-current protection
  • Green product and no Sb/Br
This device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
