Diodes 3 Terminal Positive Voltage Regulator

Manufacturer: Diodes, Inc. / Zetex
Designed for Use as a General Purpose Regulator for Distributed Power Systems:The AP78Lxx series supports a wide range of fixed output voltages making them well suited for a broad range of applications, from instrumentation to automation and most solid state electronic equipment.

Key Features:
Supply Voltage Range: 7V to 27V
- Suitable for use in a wide range of applications, from STB TV to instrumentation.
- Supports a Temperature Range: -20°C to +125°C
Fixed Voltage Outputs:
- AP78Lxx series offers fixed output voltages from 5V, 8V and 12V.
Output Current:
- AP78Lxx series can drive up to 100mA of current.
Device Protection:
- AP78Lxx series has built-in thermal overload protection, which prevents the devices from
being damaged due to excessive junction temperature.
- AP78Lxx series also contains internal short-circuit protection which limits the maximum output
- AP78Lxx series also offers a safe-area protection for the pass transistor, which reduces the
short-circuit current as the voltage across the pass transistor is increased.
Few External Components Needed:
- AP78Lxx series requires only a couple of external components to complete the circuit versus
existing competitor solutions.
