Technical Specifications

The TA48M05F has an input voltage range of typically 7V to 25V, with a recommended input voltage of 9V to 12V. The output voltage is fixed at 5V with a tolerance of ±4%. The device is available in a TO-220 or similar package and requires only a few external capacitors for stable operation. The thermal resistance is typically low, allowing for efficient heat dissipation.

The regulator's built-in protection features ensure safe and reliable operation in a wide range of environments. The thermal overload protection limits the output current when the junction temperature exceeds a safe level, preventing damage to the device. The short-circuit protection shuts down the output in case of a short circuit, protecting both the regulator and the load. The overvoltage protection safeguards the load from excessive input voltages.
