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 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 APPLICATIONS • CapFREE: No output capacitor needed, stable for all capacitive • Cordless and mobile phones • Industrial and medical equipment • Other battery-powered equipment. loads, regardless of ESR • Low 30 µVRMS noise without noise bypass capacitor • Preset output voltages to 2.5 V, 2.8 V, 3.0 V, 3.3 V and 3.6 V; other voltages available upon request. 2% output voltage accuracy • 150 mA maximum output current with current limitation • Typical dropout voltage 55 mV @ 50 mA output current • 85 µA typical ground current • Thermal-overload and short-circuit protection • PWROK pin: both power status and thermal warning indicator • PWRON pin offers logic-controlled shutdown • Maximum line regulation: 0.1%/V • Maximum load regulation: 0.02%/mA.
