LV59033M
Overview
The LV59033M is a constant-voltage power supply IC incorporating the output ON/OFF function, which offers advantages
such as small current drain when output OFF and saves power dissipation of the equipment.
Features
• 3.3V output
• Output voltage ON/OFF function with the control pin (active, high)
• Output current of 1A obtainable (V
IN
1, V
IN
