LDO takes more functions onboard
1.5A LDO incorporates shutdown, power good, programmable power good delay and bond-wire compensation on a single chip.
Microchip announces the industry's first 1.5A 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 packages (8-pin SOIC or 3 x 3mm DFN)

Microchip has announced the world's first serial EEPROM supporting the Advanced Communications Riser Special Interest Group (ACR SIG) specification.
Easy interfacing to faster microcontrollers
Microchip has added two new devices to its PIC16C92X family of 8bit one-time-programmable microcontrollers with integrated liquid-crystal display controller.
The combination of high output current (1.5A) and low output voltage (down to 0.8V) makes the MCP1727 ideally 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 140uA (typical).
In addition, the MCP1727 offers a shutdown feature that allows it to be enabled and disabled by system logic.
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, resulting 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's MCP1726 1A LDO evaluation board (part number MCP1726EV) can also be used to support development using the 1.5A MCP1727.
The MCP1727 and the evaluation board are available to purchase today.
