Microchip Technology

The MCP1701A is a CMOS low dropout positive voltage regulator with a maximum input voltage of 10V that can source up to 250 mA with a low input to output voltage differential of 380 mV at 200 mA. This low dropout voltage combined with low current consumption of 1.0 µA typical makes this part ideal for battery operated systems. This part is recommended for applications where the input voltage is between 6.0V and 10.0V. For applications where input voltages are less than 6.0V, Microchip recommends the MCP1700. The MCP1701A is offered in SOT-23-3, SOT-89-3 and TO-92-3 packages.

The MCP1702 is a CMOS low dropout positive voltage regulator with 250 mA maximum output current. MCP1702 works with input voltage of up to 13.2V and in combination with its low current consumption of 2 µA is an ideal solution for applications using multi-cell, 9V alkaline or one- or two cell lithium-ion batteries.

The MCP1711 is a very accurate CMOS low dropout (LDO) voltage regulator that can deliver up to 150 mA of current while consuming only 0.6 μA of quiescent current (typical). The LDO output is stable without the need of capacitors due to excellent internal phase compensation. Eliminating capacitors can save space overall solution cost. However, for better transient responses, the output capacitor should be added for enhanced performance. The MCP1711 has a true current foldback feature for added protection when the load decreases beyond the MCP1711’s load rating. The package options for the MCP1711 are the 4-Lead 1x1 mm UQFN and the 5-Lead SOT-23 which makes an ideal choice for small and compact applications.

MCP1722 is a dual output, high voltage, low dropout (LDO) regulator, designed to supply a μProcessor with either 3.3V or 5.0V. It has a current capability of 100mA, while also providing 10V or 12V to a motor driver with a current capability of 50 mA. These specifications make it ideal for handheld power tools with 20V battery packs. MCP1722 comes with Power Good indicators (two pins, PWG1 and PWG2) for both outputs and shutdown functionality (a single SHDN pin) that places the part in a low current consumption state, of only 4 μA. The device comes in two 8-lead DFN or SOIC packages, both with exposed pads, for improved thermal dissipation. While in operation, MCP1722 is fully protected by thermal shutdown protection and current foldback limiting.

The MCP1726 is a 1A, ceramic output cap stable, low output voltage Low Dropout Regulator (LDO) with shutdown and user-programmable delay power good functions. It is the ONLY 1A LDO on the market that incorporates shutdown, power good, and programmable power good delay features on a single device.
