LM285LPE3-1-2 Frequently Asked Questions (FAQ)
-
Texas Instruments recommends a star-grounded layout with the voltage reference at the center, and keeping the input and output traces as short as possible to minimize noise and interference.
-
To ensure stability, make sure to decouple the input and output pins with capacitors (e.g., 10uF and 100nF, respectively), and use a low-ESR capacitor (e.g., X7R or X5R) for the output capacitor.
-
The maximum power dissipation of the LM285LPE3-1-2 is 500mW. To calculate it, use the formula: Pd = (Vin - Vout) x Iout, where Vin is the input voltage, Vout is the output voltage, and Iout is the output current.
-
While the LM285LPE3-1-2 is primarily a voltage reference, it can be used as a voltage regulator in certain applications. To do so, connect the output to a resistive divider network, and use an external transistor or FET to regulate the output voltage.
-
To protect the LM285LPE3-1-2 from overvoltage and reverse voltage conditions, use a voltage clamp or a transient voltage suppressor (TVS) diode on the input pin, and consider adding a reverse-biased diode on the output pin.
