TS9015

300mA CMOS LDO

0.9V Adjustable Voltage with Enable Function

1/5

Version: D08

SOT-25

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.
