MCP1826/MCP1826S

1000 mA, Low Voltage, Low Quiescent Current

LDO Regulator

Features

Description

• 1000 mA Output Current Capability

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.

• Input Operating Voltage Range: 2.3V to 6.0V

• Adjustable Output Voltage Range: 0.8V to 5.0V

(MCP1826 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: 250 mV Typical at 1000 mA

• Typical Output Voltage Tolerance: 0.5%

• Stable with 1.0 µF Ceramic Output Capacitor

• Fast response to Load Transients

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.

• Low Supply Current: 120 µA (typ)

• Low Shutdown Supply Current: 0.1 µA (typ)

(MCP1826 only)

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.

• Fixed Delay on Power Good Output

(MCP1826 only)

• Short Circuit Current Limiting and

Overtemperature Protection

• TO-263-5 (DDPAK-5), TO-220-5, SOT-223-5

Package Options (MCP1826).

• TO-263-3 (DDPAK-3), TO-220-3, SOT-223-3

Package Options (MCP1826S).

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).

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
