DeRozan scored 29 points and the Spurs defeated Atlanta 117-111 Tuesday night for their 21st straight win at home over the depleted Hawks.
"The last couple of games, I felt like I kind of let them down, so I wanted to step up and help them out," White said.
White, in his second year, scored 23 points after scoring 20 total points in his previous four games.
The win kept San Antonio seventh in the Western Conference after Oklahoma City defeated the Los Angeles Lakers 119-103 on Tuesday behind Russell Westbrook's historic game. Westbrook joined Wilt Chamberlain as the only players in league history with at least 20 points, rebounds and assists in a game.
The Hawks, who were eliminated from the playoffs last month, entered Tuesday's game having won six of 10. Atlanta led by as many as nine points in the second half despite missing six players due to injury, before San Antonio rallied in the fourth to avoid its second straight loss at home.
"Stops win basketball games," Spurs coach Gregg Popovich said. "Sure, you've got to make shots, but when we lose these games it's because we don't make stops, especially in the fourth quarter."
Kent Bazemore had 26 points to lead the Hawks, and Alex Len added 21. Atlanta has not won in San Antonio since 1997.
"It's tough winning here, we all know that," said Hawks rookie Trae Young, who scored 15. "(But) we had chances to win."
Atlanta closed the third quarter on an 18-6 run and carried a 90-86 lead into the fourth. The Hawks made four 3-pointers in the run, including a pair by Len, their 7-foot-1 center.
The Spurs countered with a 15-4 run beginning midway through the final quarter and took a 108-104 lead with 3:39 remaining. White had seven straight points during the outburst, including his third and final 3-pointer in as many attempts.
"What you saw, that's his game," Popovich said. "He's just kind of steady, picks his spots. I loved seeing him get more confident with the 3, knocking down a couple, that's great. That's the next step for him."
White had scored six points in each of his previous two games and shot a combined 7 for 30 from the field in his past four.
"He had a couple of games where he struggled, but sometimes you've got to embrace the struggle to understand how to get out of it and what you need to do to get back to yourself," DeRozan said.
White did so, going 10 for 12 from the field for his highest output since March 12. The 24-yeard old returned to the form that made him a pleasant surprise after the Spurs were forced to move him into the starting lineup when starting point guard Dejounte Murray suffered a season-ending knee injury in the preseason.
"They were focusing a lot on DeMar, he had a big game," White said. "I knew I had to step up when the opportunity was there."
DeRozan added seven assists and seven rebounds in 38 minutes. Rudy Gay, who finished with 11 rebounds, was the only Spurs starter not to score in double figures.
Both teams got off to an efficient start, making their first three shots on their first three possessions. The Spurs closed the quarter shooting 59 percent from the field and took a 33-31 lead while the Hawks shot 48 percent.
