New products: 1.4-7V fine-adjust D30V3xMALx step-down voltage regulators
|
|
We are now offering lower-voltage versions of our D30V3x step-down voltage regulators with a precision-adjustable 1.4 V to 7 V output. As with the rest of the D30V3x line, these new regulators work with input voltages between 3.3 V and 45 V and can deliver between 1 A and 4.5 A of output current, depending on the input and output voltages. They have very low dropout voltages and feature a power-good output for identifying when the output voltage is not being maintained. They also feature an enable pin with a precise threshold for turning off the regulator, and some of the versions have additional circuitry to offer a precision-adjustable low-voltage cutoff.

Four versions are available with this new 1.4 V to 7 V output range:
- D30V30MAL – compact (0.6″ × 1.0″), double-sided assembly with precision-adjustable output and no low-voltage cutoff.
- D30V30MALCMA – compact (0.6″ × 1.0″), double-sided assembly precision-adjustable output and precision-adjustable low-voltage cutoff.
- D30V33MAL – larger (0.9″ × 1.2″), single-sided assembly with precision-adjustable output and no low-voltage cutoff. The increased heat dissipation from the larger boards let this version deliver slightly more current than the D30V30MAL.
- D30V33MALCMA – larger (0.9″ × 1.2″), single-sided assembly with precision-adjustable output and precision-adjustable low-voltage cutoff. The increased heat dissipation from the larger boards let this version deliver slightly more current than the D30V30MALCMA.
