• Manufacturer Part Number: GT2123
• Description: CMOS POSITIVE VOLTAGE REGULATOR
• Manufacturer: GTM [GTM CORPORATION]

External Resistor Divider Table
Note: Small load (greater than 2mA) is necessary as R1 or R2 is large than 50Kohm. Otherwise, output voltage probably cannot be
pulled down to 0V on disable mode
