Overview
The LA5620 is a multi-system power supply regulator IC
that includes four regulator circuits on chip: two 3.3-V
regulator circuits and two 5-V regulator circuits. The
LA5620 is optimal for use in audio and video systems that
use a microcontroller, such as MD players and stereo
components.
Functions and Features
• Two 3.3-V regulator circuits (IO= 40 mA, 150 mA)
• Two 5-V regulator circuits (IO= 1000 mA, 100 mA)
• Power on/off detection circuit
• Reset circuit
