Product Overview

The KF33BDT-TR is a Low-drop Voltage Regulator with inhibit and in a wide range of output voltages. The very low dropout voltage (0.4V) and the very low quiescent current make them particularly suitable for low noise, low power applications and especially in battery powered systems. A shutdown logic control function is available (pin 5, TTL compatible). This means that when the device is used as a local regulator, it is possible to put a part of the board in standby, decreasing the total power consumption. It requires only a 2.2µF capacitor for stability allowing space and cost saving.
  • Low quiescent current (typical 50µA in OFF mode, 500µA in ON mode)
  • Output current up to 500mA
  • Logic-controlled electronic shutdown
  • Internal current and thermal limit
  • Available in ±2% accuracy at 25°C
  • 70dB (typical) Supply voltage rejection
