Microchip has introduced what it says is the industry’s first 1,5 A LDO that incorporates shutdown, power good, programmable power good delay and bond-wire compensation on a single chip.
The MCP1727 is a highly efficient, adjustable output, low-power LDO in small, thermally-capable package (8-pin SOIC or 3 x 3 mm DFN).
The combination of high output current (1,5 A) and low output voltage (down to 0,8 V) makes the MCP1727 well-suited for powering a variety of power supply applications including high-performance embedded processors. The device offers a dropout voltage of only 300 mV (typical) at full load current, and a quiescent current of just 140 μA (typical). In addition, it offers a shutdown feature that allows it to be enabled and disabled by system logic. According to Microchip, more efficient and cost-effective designs are possible because the device is stable with a ceramic output capacitor.
The MCP1727 also has an output voltage sense pin that is used to compensate for output voltage changes due to losses in the output bond wire. This, says the company, results in faster, more accurate output voltage regulation. The power good output with user-programmable delay gives designers flexibility in power scheduling for a range of applications.
Microchip also offers an evaluation board that can be used to support development using the 1,5 A MCP1727.
