The KF25BDT-TR is a very low drop regulator available in SO-8 package and in a wide range of output voltages. The very low drop voltage (0.4 V) and the very low quiescent current make them particularly suitable for low noise, low power applications and specially 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 2.2 µF capacitor for stability allowing space and cost
saving.
STMicroelectronics recommends a thermal pad on the bottom of the package, connected to a large copper area on the PCB to dissipate heat efficiently. A minimum of 2oz copper thickness is recommended.
Ensure proper thermal management, use a stable power supply, and follow the recommended operating conditions. Also, consider using a thermistor or thermocouple to monitor the device temperature.
STMicroelectronics recommends using ESD protection devices, such as TVS diodes, on the input and output pins to prevent damage from electrostatic discharge. Follow the recommended ESD protection circuit in the application note.
Yes, but ensure the device is properly sealed and conformal coated to prevent moisture ingress. Follow the recommended storage and handling procedures to prevent moisture absorption.
STMicroelectronics recommends a soldering profile with a peak temperature of 260°C, a dwell time of 30-60 seconds, and a cooling rate of 4°C/s. Follow the recommended soldering guidelines in the application note.
