TL2844DR Frequently Asked Questions (FAQ)
-
The recommended operating voltage range for the TL2844DR is 2.7V to 5.5V.
-
To ensure stability, it's essential to follow the recommended layout and decoupling guidelines, and to use a capacitor with a value between 10nF to 100nF between the VCC and GND pins.
-
The maximum output current of the TL2844DR is 50mA per channel.
-
No, the TL2844DR is a low-dropout linear regulator, but it's not designed to be used as a voltage regulator. It's intended for use as a low-noise, low-dropout linear regulator for powering analog circuits.
-
The output voltage of the TL2844DR can be calculated using the formula: VOUT = VREF x (1 + R1/R2), where VREF is the internal reference voltage (1.24V), and R1 and R2 are the resistors used to set the output voltage.
