Overview
INTEGRATED CIRCUITS SA57000-XX CapFREE™ 150 mA, low-noise, low dropout regulator with thermal protection Product data Supersedes data of 2001 Jul 12 File under Integrated Circuits, Standard Analog 2001 Aug 27 Philips Semiconductors Philips Semiconductors Product data CapFREE™ 150 mA, low-noise, low dropout regulator with thermal protection SA57000-XX GENERAL DESCRIPTION The CapFREE™ SA57000 is the first in a new family of unique low dropout regulators.
It needs no external capacitors, offers a low output noise voltage of 30 µVRMS, and an ultra-low dropout voltage of 55 mV @ 50 mA output current.
To accommodate high density layouts, it is packaged in the small footprint 5 leaded SOT23-5 (SO5).
It is ideal for all portable and cellular phone applications.
Additional features include power and thermal shutdown, output current limitation, power OK status, thermal warning, and external logic-controlled on-off via the PWRON pin.
FEATURES • CapFREE: No output capacitor needed, stable for all capacitive loads, regardless of ESR APPLICATIONS • Low 30 µVRMS noise without noise bypass capacitor • Preset output voltages to 2.
