Product Overview
KF50BDT-TR is a KF series very low drop voltage regulator with inhibit. The very low dropout voltage (0.4V) and the very low quiescent current make it particularly suitable for low noise, low power applications and especially in battery-powered systems. When the device is used as a local regulator, it is possible to put a part of the board on standby, decreasing the total power consumption. It requires only a 2.2µF capacitor for stability allowing space and cost saving.
- Very low dropout voltage (0.4V)
- Very low quiescent current (typ. 50µA in OFF mode, 500µA in ON mode)
- Logic-controlled electronic shutdown
- Internal current and thermal limit
- Only 2.2µF for stability
- Supply voltage rejection is 70db (typical)
- Temperature range from -40 to 125°C
- 5V output voltage, 20V maximum operating input voltage (IO = 500mA)
- Output noise voltage is 50µV typ (B = 10Hz to 100KHz)
- DPAK package
