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: 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

Note) 1. *1: Except for the operating ambient temperature and storage temperature, all ratings are for T
a
= 25C.
*2: When V
CC
of 35 V is applied, the overvoltage protection of ASO protection circuit may shut off the output.
*3: Since this IC has incorporated a current limiter, the current value does not exceed the rating.
*4: When Tj exceeds 150
C (designed value), the internal circuit cuts off the output. 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.
