ADP1710AUJZ-3.0-R7

ADP1710AUJZ-3.0-R7 is a low dropout linear regulator that operates from 2.5V to 5.5V and provides up to 150mA of output current. Utilizing a novel scaling architecture, the ground current drawn is a very low 40μA, when driving a 100μA load, making the ADP1710 ideal for battery-operated portable equipment. The ADP1710 is optimized for stable operation with small 1μF ceramic output capacitors, allowing for good transient performance while occupying minimal board space. An enable pin controls the output voltage on both devices. There is also an under-voltage lockout circuit on both devices, which disables the regulator if IN drops below a minimum threshold. An internal soft start gives a typical start-up time of 80μs. Short-circuit protection and thermal overload protection circuits prevent damage to the devices in adverse conditions. Applications include mobile phones, digital camera and audio devices, portable and battery-powered equipment, post dc-dc regulation.
