AN78MxxNSP Series
3-pin positive output voltage regulator (500 mA type)
I Overview
The AN78MxxNSP series is a 3-pin fixed positive
output type monolithic voltage regulator housed in surface
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.
I Features
• Output voltage: 5V,6V,7V,8V,9V,10V,12V,15V,18 V
• Built-in overcurrent limit circuit
• Built-in thermal overload protection circuit
• Built-in ASO (area of safe operation) protection circuit

I Electrical Characteristics at Ta = 25°C (continued)
• AN78M08NSP (8 V type)
The specified condition Tj = 25°C means that the test should be carried out within so short a test time (within 10 ms)
that the characteristic value drift due to the chip junction temperature rise can be ignored.
Unless otherwise specified, VI = 14 V, IO = 350 mA, CI = 0.33 µF and CO = 0.1 µF
