Applications
Description
The MCP1826/MCP1826S is a 1000 mA Low Dropout
(LDO) linear regulator that provides high current and
low output voltages. The MCP1826 comes in a fixed or
adjustable output voltage version, with an output
voltage range of 0.8V to 5.0V. The 1000 mA output cur-
rent capability, combined with the low output voltage
capability, make the MCP1826 a good choice for new
sub-1.8V output voltage LDO applications that have
high current demands. The MCP1826S is a 3-pin fixed
voltage version.
The MCP1826/MCP1826S is stable using ceramic
output capacitors that inherently provide lower output
noise and reduce the size and cost of the entire
regulator solution. Only 1 μF of output capacitance is
needed to stabilize the LDO.
Using CMOS construction, the quiescent current
consumed by the MCP1826/MCP1826S is typically
less than 120 μA over the entire input voltage range,
making it attractive for portable computing applications
that demand high output current. The MCP1826
versions have a Shutdown (SHDN) pin. When shut
down, the quiescent current is reduced to less than
0.1 μA.
On the MCP1826 fixed output versions the scaled-
down output voltage is internally monitored and a
power good (PWRGD) output is provided when the
output is within 92% of regulation (typical). The

PWRGD delay is internally fixed at 200 μs (typical).
The overtemperature and short circuit current-limiting
provide additional protection for the LDO during system
fault conditions.
