MCP1824/MCP1824S

300 mA, Low Voltage, Low Quiescent Current LDO Regulator

Features

Description

• 300 mA Output Current Capability

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.

• Input Operating Voltage Range: 2.1V to 6.0V

• Adjustable Output Voltage Range: 0.8V to 5.0V

(MCP1824 only)

• Standard Fixed Output Voltages:

- 0.8V, 1.2V, 1.8V, 2.5V, 3.0V, 3.3V, 5.0V

• Other Fixed Output Voltage Options Available

Upon Request

• Low Dropout Voltage: 200 mV Typical at 300 mA

• Typical Output Voltage Tolerance: 0.4%

• Stable with 1.0 µF Ceramic Output Capacitor

• Fast Response to Load Transients

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.

• Low Supply Current: 120 µA (typical)

• Low Shutdown Supply Current: 0.1 µA (typical)

(MCP1824 only)

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.

• Fixed Delay on Power Good Output

(MCP1824 only)

• Short Circuit Current Limiting and

Overtemperature Protection

• 5-Lead Plastic SOT-223, SOT-23 Package

Options (MCP1824)

• 3-Lead Plastic SOT-223 Package Option

(MCP1824S)

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).

Applications

• High-Speed Driver Chipset Power

• Networking Backplane Cards

• Notebook Computers

The overtemperature and short circuit current-limiting

provide additional protection for the LDO during system

fault conditions.

• Network Interface Cards

• Palmtop Computers

• 2.5V to 1.XV Regulators
