Features

* are also included in this device. Features
* Inductorless solution uses only 4 small ceramic
* capacitors. True input-output and output-input disconnect. Up to 180 mA output current capability (5V). Selectable 4.1V, 4.5V or 5.0V output. Pre-re

Applications

* that require the regulated output bus to be driven by another supply while the LM2757 is shut down. A perfect fit for space-constrained, battery-operated applications, the LM2757 requires only 4 small, inexpensive ceramic capacitors. LM2757 is a tiny 1.2 mm X 1.6 mm 12
* bump micro SMD device.
