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.
I Features
• Output voltage: 5V,6V,7V,8V,9V,10V,12V,15V,18V
• Built-in overcurrent limit circuit
• Built-in thermal overload protection circuit
• Built-in ASO (area of safe operation) protection circuit
