LV59033M
Overview
3.3V Constant-Voltage Power Supply IC
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 (VIN1, VIN2
≥
4.3V)
•
Small current drain (1μA max) when output OFF and optimum for power saving
•
MFP8 (200mil) package, ensuring easy mounting design
•
Full compliment of protection circuits incorporated (including overcurrent protection, thermal protection)
