The AN78M00 and the AN78M00F series are 3-pin
fixed positive output voltage regulators. Stabilized fixed
output voltage is obtained from unstable DC input voltage 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.

Note 1) The specified condition Tj=25˚C means that the test should be carried out with the test time so short (within 10ms) that the
drift in characteristic value due to the rise in chip junction temperature can be ignored.
