UA78S40PC Frequently Asked Questions (FAQ)
-
The maximum operating temperature range for the UA78S40PC is -40°C to 125°C.
-
To ensure stability, a minimum output capacitance of 100nF and a minimum ESR of 0.5 ohms are recommended. Additionally, the input voltage should be well-regulated and the device should be decoupled with a 10uF capacitor.
-
The maximum input voltage that the UA78S40PC can handle is 35V. Exceeding this voltage may cause damage to the device.
-
The output voltage of the UA78S40PC can be calculated using the formula: Vout = Vref x (1 + R1/R2), where Vref is the internal reference voltage (approximately 2.5V) and R1 and R2 are the resistors used in the voltage divider network.
-
The quiescent current of the UA78S40PC is typically around 5mA, but can vary depending on the input voltage and output load.
