... When shutdown, power con- sumption drops nearly to zero. Regulator ground current in- creases only slightly in dropout, further prolonging battery life. Key features of GM6155 include a reference bypass pin to improve its excellent low-noise performance, re- versed-battery protection, current limiting, and over- temperature shutdown ...

... No-Load Stability GM6155 will remain stable and in regulation with no load (other than the internal voltage divider) unlike many other voltage regulators. This is especially important in CMOS RAM keep-alive applications. Thermal Considerations Gm6155 is designed to provide 150mA of continuous current in a very small package ...

... EN (pin 3) connected to IN (pin 1) for an application where enable/ shutdown is not required 2.2µF minimum. OUT Adjustable Regulator Applications The GM6155 can be adjusted to a specific output voltage by using two externa resistors (Figure 5). The resistors set the output voltage based on the following equation Recommended ...

This equation is correct due to the configuration of the bandgap reference. The bandgap voltage is relative to the output, as seen in the block diagram. Traditional regulators normally have the reference voltage relative to ground and have a different ...
