Description
Pololu 5V Step-Down Voltage Regulator D30V30F5, 3.4A Continuous Output
Efficient 80-95% typical efficiency
Low dropout voltage
Integrated safety features
Power-save mode available
The Pololu 5V Step-Down Voltage Regulator D30V30F5, 3.4A Continuous Output is a synchronous buck voltage regulator designed to produce a lower, regulated output voltage from input voltages up to 45 V. These regulators are highly efficient compared to linear voltage regulators, particularly when there is a significant difference between the input and output voltages. The device is capable of supporting continuous output currents ranging from 3 A to 4 A, with the exact current depending on the input and output voltages. The output current availability generally decreases as the input and output voltages increase.
The D30V30F5 model specifically provides a fixed output of 5 V with a 4% accuracy rate. It boasts a typical efficiency of 80% to 95%, which varies based on the input voltage, output voltage, and load. The regulator features a very low dropout voltage and operates at a switching frequency of approximately 700 kHz under heavy loads. It includes a power-save mode to enhance light load efficiency by reducing the switching frequency and maintains a low quiescent current. The enable input comes with a precise cutoff threshold to disconnect the load and transition the regulator into a low-power state with minimal power draw.
Additional features include a "power good" output that signals when the regulator is unable to maintain the output voltage adequately, frequency spread spectrum operation to reduce peak EMI noise, and under-voltage lockout protection. The soft-start feature is designed to limit inrush current and allow the output voltage to ramp up gradually. The regulator also incorporates integrated reverse-voltage protection up to 40 V, over-current and short-circuit protection, and over-temperature shutoff for enhanced safety and durability. Its compact dimensions allow for easy integration into a variety of applications.
The regulator includes six connections: power good (PG), enable (EN), input voltage (VIN), output voltage (VOUT), and two ground (GND) connections. The PG indicator is an open-drain output that requires an external pull-up resistor to function. The EN pin controls the low-power sleep state of the regulator, and the input voltage, VIN, powers the regulator with an effective lower limit determined by the output voltage plus the regulators dropout voltage. VOUT is the regulated output voltage, and the included hardware is compatible with standard prototyping arrangements.
During normal operation, this product can get hot enough to burn you. Take care when handling this product or other components connected to it.

If you are not satisfied for whatever reason with a Product you bought on the Site, it is possible to return it for refund within 30 days from the date you received it unless otherwise indicated in the Product listing. You must first advise the Vendor associated with your order in your account to obtain a return authorization (‘’RA’’) number before returning a Product. (‘’RA’’) numbers are valid for 30 days, within which time the returned Products should be received by the Vendor. No returns will be accepted without having previously obtained an (‘’RA’’) number. The Product must then be returned in its original packaging (in perfect condition for resale) with its receipt and your (‘’RA’’) number. Reimbursement will be denied for any Products which do not conform to the above mentioned conditions.
Build-it-yourself Robot Parts are not refundable once assembled. Robots & Kits requiring assembly or soldering are also not refundable once assembled, soldered or modified in any way. All sales of robotic software and apps are final and cannot be refunded or exchanged. Returns are not accepted on special orders and clearance items except when they are found defective, in which case the Product may be repaired or replaced at the Vendor’s discretion. 20% Restocking fees may apply if you are returning a large quantity of the same Product that was ordered specifically for you from the manufacturer.
Please note that all items will be reimbursed within 7 to 14 days of receiving the Product (shipping fees excluded). You must also cover the cost of returning the Product. Shipping fees will only be refunded if the return is a result of a shipping error on our part. Cleaning fees of USD 100 may also be charged if a domestic robot is returned and has not been properly cleaned.
