SA57000-25D-CapFREE 150mA, Low Noise, Thermal Protector Low Dropout Regulator
The CapFREEE SA57000 is the first in a new unique family of low dropout voltage regulators. It requires no external capacitors and provides a low 30 mVRMS output noise voltage and ultra-low dropout voltage of 55 mV @ 50 mA output current. To accommodate high density layouts, it is packaged in a small leaded footprint of 5 SOT23-5 (SO5). It is ideal for all portable and mobile phone applications. Other features include, output power and thermal shutdown current limit, power supply OK status, thermal warning and external logic control switch via PWRON pin.
