LV59018M
Overview
For Potable Electronic Devices
1.8V Constant-Voltage Power Supply IC
The LV59018M is a constant-voltage power supply IC for potable electronic devices 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
* 1.8V output * Output voltage ON/OFF function with the control pin (active, high) * Output current of 1A obtainable (VIN1, VIN2 2.8V) * Small current drain (1A 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)
