ADP1711

The ADP1710/ADP1711 are low dropout linear regulators that operate from 2.5 V to 5.5 V and provide up to 150 mA of output current. Utilizing a novel scaling architecture, ground current drawn is a very low 40 A, when driving a 100 A load, making the ADP1710/ADP1711 ideal for battery-operated portable equipment.

The ADP1710/ADP1711 are each available in sixteen fixed output voltage options. The ADP1710 is also available in an adjustable version, which allows output voltages that range from 0.8 V to 5 V via an external divider. The ADP1711 allows for a reference bypass capacitor to be connected, which reduces output voltage noise and improves power supply rejection.

The ADP1710/ADP1711 are optimized for stable operation with small 1 F 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 80 s. Short-circuit protection and thermal overload protection circuits prevent damage to the devices in adverse conditions. Both the ADP1710/ADP1711 are available in tiny 5lead TSOT packages, for the smallest footprint solution to all your power needs.
