LA5643 Monolithic Linear IC
Multi-Power Supply System Regulator
Overview
The LA5643 is a multi-power supply IC that provides one 3.3V regulator circuits as well as two 5V regulator circuits.
The LA5643 is optimal for MD players and other applications.
Functions
• 3.5V regulator circuit incorporated (IO=150mA)
• Two 5V regulator circuits incorporated (IO=1A,100mA)
• With power-down detector circuit
• Reset circuit operating on the VBAK voltage
• Small current dissipation of reset circuit (3.5µA typ during backup)
• Conversion of a 3.5V regulator into a 3.3V regulator through short-circuiting of ADJ pin with SYS3.5 pin
