The MCP1811/12 devices are 150 mA (MCP1811) and 300 mA (MCP1812) low dropout (LDO) linear regulators that provide high-current and low-output voltages while maintaining an ultra-low 250 nA of quiescent current during device operation. In addition, the MCP1811B/12B can be shut down for 5 nA (typical) supply current draw. The MCP1811/12 family comes in nine standard fixed output-voltage versions: 1V, 1.2V, 1.8V, 2.0V, 2.5V, 2.8V, 3.0V, 3.3V, and 4.0V. The 150/300 mA output current capability, combined with the low output-voltage capability, make the MCP1811/12 device family a good choice for new ultra-long-life LDO applications that have high-current demands, but require ultra-low power consumption during sleep periods. The MCP1811/12 is stable with ceramic output capacitors that inherently provide lower output noise and reduce the size and cost of the entire regulator solution. Only 1 μF (2.2 μF for MCP1812) of output capacitance is needed to assure the stability of the system with a low noise output. The MCP1811/12 can be paired with other ultra-low current devices, such as Microchip’s nanoWatt eXtreme Low Power (XLP) technology devices, for a complete ultra-low-power solution.

The MCP1845S is a 300 mA, ceramic output cap stable, low output voltage, Low Dropout Voltage Regulator. It is a part of the family of LDOs that includes 500 mA MCP1825S, 1A MCP1826S and 1.5A MCP1827S. MCP1824S comes in thermally capable SOT223 package.

The MCP1825/MCP1825S is a 500 mA Low Dropout (LDO) linear regulator that provides high current and low output voltages. The MCP1825 comes in a fixed or adjustable output voltage version, with an output voltage range of 0.8V to 5.0V. The 500 mA output current capability, combined with the low output voltagecapability, make the MCP1825 a good choice for new sub-1.8V output voltage LDO applications that have high current demands. The MCP1825S is a 3-pin fixed voltage version. The MCP1825/MCP1825S 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.

The MCP1826S is a 1A, ceramic output cap stable, low output voltage, Low Dropout Regulator (LDO). It is part of the family of LDOs that includes 500 mA MCP1825S and 1.5A MCP1827S. The MCP1826S comes in thermally enhanced DDPAK-3 and TO-220-3 packages as well as space-efficient SOT223-3 package.

The MCP1827S is a 1.5A, ceramic output cap stable, low output voltage, Low Dropout Regulator (LDO). It is part of the family of LDOs that includes 500 mA MCP1825S and 1A MCP1826S. MCP1826S comes in thermally enhanced DDPAK-3 and TO-220-3 packages as well as space-efficient SOT223-3 package

MCP18480 is a -48V Hot Swap Controller with fully configurable features. This Hot Swap Controller have OVLO, UVLO protection features on top of Foldback Current Limiting and Circuit Breaker features. Although ideally suited optical switch backplanes, the MCP18480 can also be used in any -48V backplanes or whenever inrush current control is required.

The MCP19035 is a small, analog-based PWM controller family with integrated synchronous MOSFET drivers offering outstanding transient performance. The MCP19035 operates over a wide 4.5 - 30Vdc range, has both a 300 kHz or 600khz switching-frequency option, and offers a factory-adjustable dead-time setting, allowing designers to optimize the performance across a wide selection of MOSFET devices. The MCP19035 family, when combined with Microchip’s MCP87xxx MOSFETs, or any low-FOM MOSFET, produces high-efficiency (>96%) DC/DC power-conversion solutions.

The MCP19110 is a mid-voltage (4.5-32V) analog-based PWM controller with an integrated 8-bit PIC(R) Microcontroller. This unique product combines the performance of a high-speed analog solution, including high-efficiency and fast transient response, with the configurability and communication interface of a digital solution. Combining these solution types creates a new family of devices that maximizes the strengths of each technology to create a more cost-effective, configurable, high-performance power conversion solution. The MCP1911x family, when combined with Microchip's MCP87xxx MOSFETs, or any low-FOM MOSFET, produce high-efficiency (>96%) DC/DC power-conversion solutions. Please Note: Our MCP19110 is a smaller, functionally equivalent version of our MCP19111. The MCP19111 development tools, including both hardware and software tools, provide a convenient and powerful development platform upon which to develop and evaluate your power supply design.
