Alternate Parts for LP339DR
This table gives cross-reference parts and alternative options found for LP339DR. The Form Fit Function (FFF) tab will give you the options that are more likely to serve as direct pin-to-pin alternates or drop-in parts. The Functional Equivalents tab will give you options that are likely to match the same function of LP339DR, but it may not fit your design. Always verify details of parts you are evaluating, as these parts are offered as suggestions for what you are looking for and are not guaranteed.
LP339DR Frequently Asked Questions (FAQ)
-
The LP339DR can operate from -40°C to 125°C, but the maximum junction temperature (TJ) should not exceed 150°C.
-
To ensure stability, use a minimum output capacitance of 10uF, and a maximum ESR of 1 ohm. Also, keep the input and output capacitors close to the device and use a low-ESR capacitor for the output.
-
The LP339DR can operate with an input voltage as low as 3.5V, but the recommended minimum input voltage is 4.5V for optimal performance.
-
The LP339DR is designed for low-current applications (up to 150mA). For high-current applications, consider using a different device or adding an external transistor to boost the current capability.
-
The output voltage of the LP339DR is determined by the resistive divider network (R1 and R2) connected to the ADJ pin. Use the formula: Vout = (1 + R2/R1) x Vref, where Vref is the internal reference voltage (1.24V).
