AN7900T/AN7900F Series3-pin Negative Output Voltage Regulators (1A Type)s Overview The AN7900T/AN7900F series is 3-pin fixed negativeoutput type monolithic voltage regulators.A stabilized fixed negative output voltage is obtained froman unstable DC input voltage without using any externalparts. Eleven types of fixed output voltage are availablefrom –5V through –10V, –12V, –15V, –18V, –20V, and–24V. They can be used widely as power circuits with acurrent capacitance of up to 1A.AN7900T Series10.5±0.510.4±0.5ø3.78.7±0.36.7±0.252.9±0.1Unit : mm1.4±0.14.51.4±0.250.8±0.22.540.10.45+– 0.0513.6±0.252.5±0.25s Features• No external components• Output voltage :–5V, –6V, –7V, –8V, –9V, –10V, –12V, –15V, –18V, –20V, –24V• Overcurrent limit circuit built-in• Thermal over-load protection built-in• Area of safe operation (ASO) circuit built-in4.5±0.31 : Common2 : Input1233 : OutputJEDEC: TO-220AB (HSIP003-P-0000)AN7900F Seriesø5.3(4.3)10.5±0.3ø3.1±0.116.7±0.3Unit : mm2.77±0.3(1.73)4.2±0.253.8±0.250.4+0.1– 0.0517.0±0.2513.6±0.254.5±0.251.4±0.20.8±0.2(0.4)2.0±0.2532.54122.5±0.251 : Common4.5±0.32 : Input3 : OutputTO-220 Full Pack Package (HSIP003-P-0000A)s Block Diagram1R1+VoltageReferenceError Amp.R2–StarterThermalProtectionCurrentLimiterRSC2InputQ13OutputCommonPass Tr. 8.7±0.31
