AN7900T/AN7900F Series
3-pin Negative Output Voltage Regulators (1A Type)
s
Overview
The AN7900T/AN7900F series is 3-pin fixed negative
output type monolithic voltage regulators.
A stabilized fixed negative output voltage is obtained from
an unstable DC input voltage without using any external
parts. Eleven types of fixed output voltage are available
from –5V through –10V, –12V, –15V, –18V, –20V, and
–24V. They can be used widely as power circuits with a
current capacitance of up to 1A.
