2010年4月19日 · Using a LM317 requires 2 to 3 resistors, 7803 does not. Am I missing something? The LM317 is a linear regulator - so depending on your input voltage, you could dissipate a lot of heat through it, and waste power. The 7803 is a switching regulator - which is an entirely different topology for voltage regulators.

2020年7月28日 · ADI's LTC7803 is a low I Q, high performance, 100% duty cycle synchronous step-down switching regulator controller that operates up to a 40 V input supply range. Spread spectrum frequency modulation operation helps reduce EMI peaks.
