The LD111733CTR is a linear regulator having a fixed output voltage of 3.3V, a maximum current of 1.34A, and a SOT-223 SMD packaging. The linear regulator's power dissipation is reduced by the low dropout voltage of 1V (typical @100mA). This is helpful in situations where a linear regulator's improved line regulation and energy economy are required. The supply voltage rejection is 75db, and the output voltage is 100V with minimal noise. For stability, the LD1117S33CTR just requires a single 10uF capacitor.
