AP731x and AP733x - Low drop out regulators from Diodes Incorporated improve system stability and transient response

The AP731x and AP733x are 150mA and 300mA CMOS LDOs, respectively, with a wide input voltage range of 2 to 6V that address both fixed and adjustable output voltage requirements. Fixed output voltage LDOs cover the range between 1.0 and 3.3V, while adjustable devices support the output voltage range between 0.8V to 5V.

With an output accuracy specified at 2%, the LDOs maintain consistent regulation for variations in specified temperature, line voltage and load conditions. The devices are rated for full industrial temperature range operation, from -40ºC to +85ºC.

The LDOs' built-in over-current, over-temperature and short-circuit protection further improves circuit robustness and reliability. In portable and low power applications in particular, the devices' quiescent current rating of 55µA provides attractive power saving opportunities.

Applications to benefit from these versatile LDOs include XDSL routers, wireless LAN cards, desktop and notebook computers, mouse and keyboard products and battery powered equipment.

Offered with industry standard pin-outs, the LDOs are being made available by Diodes in a range of green package options including SOT23, SOT25 and the PCB space and height saving DFN2020-6.
