Features • 5.0V and 3.3V constant voltage outputs composed of 2-hold mode charge pump boost circuit. • Built-in overload detection function for constant voltage output circuit. Overcurrent limit (70mA) operates with 1.5Ω external resistor. Constant voltage output after time-latch: OFF (100msec). • Reverse flow prevention function is built into constant voltage output. (An external diode for reverse flow prevention is not necessary.) There is no reverse current from 5.0V output to VCC. The current flow into 3.
