Voltage Regulators
AN78xxNSP Series
3-pin positive output voltage regulator (1 A type)
I
Overview
The AN78xxNSP series is a 3-pin fixed positive output
type monolithic voltage regulator housed in surface mount-
ing package. Stabilized fixed output voltage is obtained
from unstable DC input voltage with using minimum ex-
ternal components. 9 types of fixed output voltage are avail-
able; 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 1 A.

Note) 1. *1: Except for the operating ambient temperature and storage temperature, all ratings are for T

25°C.
*2: The power dissipation shown is the value for the independent IC without a heat sink at T
a
=
85°C.
When Tj exceeds 150°C (designed value), the internal circuit cuts off the output.
2. This IC is not suitable for car electronics equipment.
