| 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.
