L296P FAQs

1.Q: What related parts can replace the L296P?

A: Alternatives include ST’s L4970A (lower current) or L298 (dual H-bridge driver). For newer designs, consider ST’s buck regulators with higher efficiency (e.g., ST1S10).

2.Q: Does the L296P comply with industry certifications like RoHS?

A: The L296P is not RoHS-compliant (Reach Compliance Code: "not_compliant"). It has an ECCN of EAR99 and HTS code 8542.39.00.01.

3.Q: What are the recommended operating conditions for the L296P?

A: Operate at 9V–35V input, ≤7A output current, and ambient temperatures below 125°C. Ensure adequate cooling for stable performance.

4.Q: What is the thermal resistance of the L296P’s package?

A: The Multiwatt-15 package has a thermal resistance (junction-to-ambient) of ~15°C/W (typical). Proper heatsinking is required for high-current operation.

5.Q: What is the absolute maximum input voltage for the L296P?

A: The absolute maximum input voltage is 46V. Exceeding this may damage the device. The nominal operating range is 9V–35V.

6.Q: What are typical applications for the L296P?

A: It’s used in power supplies, industrial systems, automotive electronics, and high-current DC-DC converters where efficient step-down voltage regulation is needed.

7.Q: What are the key features of the L296P regulator?

A: The L296P features a 7A output current, 9V–46V input range, 200kHz switching frequency, voltage-mode PWM control, and buck (step-down) configuration. It’s designed for high-current applications.

8.Q: What is the pinout configuration of the L296P switching regulator?

A: The L296P has a 15-pin Multiwatt-15 package (Zig-Zag through-hole). Key pins include Vin (input voltage), Vout (output), Feedback (FB), Enable (EN), and ground (GND). Refer to the datasheet for the full pinout diagram.
