Applications
Description
The MCP1824/MCP1824S is a 300 mA Low Dropout
(LDO) linear regulator that provides high current and
low output voltages. The MCP1824 comes in a fixed or
adjustable output voltage version, with an output
voltage range of 0.8V to 5.0V. The 300 mA output
current capability, combined with the low output voltage
capability, make the MCP1824 a good choice for new
sub-1.8V output voltage LDO applications that have
high current demands. The MCP1824S is a 3-pin fixed
voltage version.
The MCP1824/MCP1824S 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 MCP1824/MCP1824S 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 MCP1824
versions have a Shutdown (SHDN) pin. When shut
down, the quiescent current is reduced to less than
0.1 μA.
On the MCP1824 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 110 μs (typical).
The overtemperature and short circuit current-limiting
provide additional protection for the LDO during system
fault conditions.
