MCP1824/MCP1824S

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.
