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.
