Overview
The LA5613 is an IC that includes an independently
on/off switchable 5-V/0.7-A low-saturation regulator, an
11.3-V/0.3-A ripple filter, and a control amplifier on chip.
It is optimal for use in VCR and similar products.
Functions and Features
• 5-V/0.7-A low-saturation regulator
(Includes an on/off function.)
• 11.3-V/0.3-A ripple filter (Includes an on/off function.)
• Switching regulator control amplifier
• Includes input overvoltage and thermal protection
circuits on chip.

• The relationship VCC1 ≥ VCC2 must hold at all times when power is applied.
• Power should be applied to VCC1 and VCC2 simultaneously. Do not use this IC with only one or the other voltage
applied.
• This IC will be destroyed if the VO1 output load is shorted. Do not short the outputs of this IC.
