General Description
The TS9015 is a low dropout voltage linear regulator. There are device designed specifically for battery-operated
systems. Ground current is very small as 50uA(typ), that significantly extending battery life. Low power
consumption and high accuracy is achieved through CMOS and programmable fuse technologies. Output voltage
is able to adjust from 1V to 6V. The TS9015 consists of a high-precision voltage reference, and error correction
circuit, and a current limited output driver. With good transient responses, output remains stable even during load
changes. The EN input enables to be turned off, resulting in reduced power consumption.
TS9015 have high ripple rejection ratios, a 470pF capacitor from the Bypass pin to ground to reduces noise
present on the internal reference, which in turn significantly reduces output noise. If output noise is not a concern,
the Bypass pin may be left unconnected. Larger capacitor values can be used, but the results in a longer time
period to rate output voltage when power is initially applied.
