AX7805/09/12
3-Terminal Fixed Negative Voltage Regulator
GENERAL DESCRIPTION
The AX7805/09/12 series voltage regulators are monolithic integrated circuits
designed as fixed-voltage regulators for a wide variety of applications including local,
on-card regulation. These regulators employ internal current limiting, thermal shutdown, and
safe-area compensation. With adequate heatsink they can deliver output currents up to 1
ampere. Although designed primarily as a fixed voltage regulator, these devices can be
used with external components to obtain adjustable voltages and currents.
FEATURES
- Output Voltage Range 5 to 24V
- Output current up to 1A
- No external components required
- Internal thermal overload protection
- Internal short-circuit current limiting
- Output transistor safe-area compensation
- Output voltage offered in 4% tolerance
PIN ASSIGNMENT
The packages of AX7805/09/12 are TO220-3L and TO252-3L; the pin assignment is given by:
