The MCP1790/MCP1791 regulator provides up to 70 mA
of current. The input operating voltage range is specified
from 6.0V to 30V continuous, 48V absolute max, making
it ideal for automotive and commercial 12/24 VDC
systems.
The MCP1790/MCP1791 has a tight tolerance output
voltage load regulation of ±0.2% (typical) and a very
good line regulation at ±0.0002%/V (typical). The regulator
output is stable with ceramic, tantalum, and electrolytic
capacitors. The MCP1790/MCP1791 regulator
incorporates both thermal and short circuit protection.
The MCP1790 is the 3-pin version of the MCP1790/
MCP1791 family. The MCP1791 is the 5-pin version
and incorporates a Shutdown input signal and a Power
Good output signal.
The regulator is specifically designed to operate in the
automotive environment and will survive +48V (43.5V
±10%) load dump transients and double-battery jumps.
The device is designed to meet the stringent quiescent
current requirements of the automotive industry. The
device is also designed for the commercial low voltage
fire alarm/detector systems which use 24 VDC to supply
the required alarms throughout buildings. The low
ground current, 110 μA (typ.), of the CMOS device will
provide a power cost savings to the end users over
similar bipolar devices. Typical buildings using hundreds
of 24V powered fire and smoke detectors can
see substantial savings on energy consumption and
wiring gage reduction compared to bipolar regulators.
The MCP1790 device will be offered in the 3-pin
DD-PAK, and SOT-223 packages.
The MCP1791 device will be offered in the 5-pin
DD-PAK, and SOT-223 packages.
The MCP1790/MCP1791 will have a junction temperature
operating range of -40°C to +125°C.
