Voltage Regulators AN78MxxNSP Series 3-pin positive output voltage regulator (500 mA type) Overview Unit: mm 6.500.20 The AN78MxxNSP series is a 3-pin fixed positive 5.300.10 (4.35) output type monolithic voltage regulator housed in surface (3.00) 1.000.20 mounting package. Stabilized fixed output voltage is ob- tained from unstable DC input voltage with using mini- mum external components. 9 types of fixed output volt- age are available 5 V, 6 V, 7 V, 8 V, 9 V, 10 V, 12 V, 15 V and 18 V. They can be used widely in power circuits with current capacity up to 500 mA. 2 1 3 0.750.10 +0.10 2.30 Features 0.55 0.05 4.600.10 0.100.10 Output voltage: 5 V, 6 V, 7 V, 8 V, 9 V, 10 V, 12 V, 15 V, 18 V Built-in overcurrent limit circuit Built-in thermal overload protection circuit Built-in ASO (area of safe operation) protection circuit SP-3SU Note) The package of this product will be changed to lead-free type (SP-3SUA).

Note that the relationship between IC * power dissipation and the ambient temperature must follow the derating curve. 2. This IC is not suitable for car electronics equipment. Electrical Characteristics at T = 25C a AN78M05NSP (5 V type) The specified condition T = 25C means that the test should be carried out within so short a test time (within 10 ms) j that the characteristic value drift due to the chip junction temperature rise can be ignored.
