fixed positive output voltage regulators. Stabilized fixed
output voltage is obtained from unstable DC input volt-
age without using any external components. 11 types of
fixed output voltage are available;5V, 6V, 7V, 8V, 9V, 10V,
12V, 15V, 18V, 20V and 24V. They can be used widely in
power circuits with current capacitance up to 500mA.
