It has a bypass pin option which allows users to decouple the bandgap reference for reducing the output noise. Low dropout voltage and low quiescent current(70A typ.) make them ideal for battery powered applications. The SP6265 is available with a wide variety of standard voltage options and can be trimmed to .5% accuracy. For protection purposes, SP6265 has a thermal shutdown feature to prevent device failure under the "worst" operating conditions.

Mar2-07 Rev O SP6265 Dual Low-Dropout CMOS Voltage Regulator (c) 2007 Sipex Corporation 6 Detailed Description The SP6265 is low-dropout, low quiescent-current linear regulator designed primarily for battery-powered applications. These parts are available with preset output voltage ranging from .8V to .V, and the parts can supply loads up to 50mA. internal P-Channel Pass Transistor The SP6265 features two P-Channel MOSFET pass transistors. A P-Channel MOSEFT provides several advantages over similar designs using PNP pass transistors, including longer battery life. It requires no base drive, which reduces quiescent current significantly. The SP6265 only consumes 70A of quiescent current whether in dropout, light-load, or heavyload applications. Shutdown SP6265A & SP6265B The SP6265A and SP6265B have a single shutdown control input(EN). Drive EN low to shut down both outputs, reducing supply current to 0.A. Connect EN to a logichigh, or IN, for normal operation. SP6265F-SP6265M The SP6265F-SP6265M have independent shutdown control inputs (EN and EN2). Drive EN low to shutdown VOUT. Drive EN2 low to shut down VOUT2. Drive both EN and EN2 low to shut down the entire chip, reducing supply current to 0.A. Connect both EN and EN2 to a logichigh, or IN, for normal operation. Current Limit The SP6265 contains two independent current limiters, one for each regulator, which monitor and control the pass transistor' s gate voltage, limiting the guaranteed maximum output current to 80mA minimum. The output can be shorted to ground for an indefinite time without damaging the part. Thermal-Overload Protection Thermal -overload protection limits total power dissipation in the SP6265. When the junction temperature exceeds TJ=50oC, the thermal sensor signals the shutdown logic, turning off the pass transistor and allowing the IC to cool. Application information Capacitor Selection and Regulator Stability Use a F capacitor on the SP6265 input and a F capacitor on the outputs. Larger input capacitor values and lower ESRs provide better supply noise rejection and line transient response. PSRR and Operation from Sources Other than Batteries The SP6265 is designed to deliver low dropout voltages and low quiescent current in battery powered systems. Power-supply rejection is 5dB at low frequencies.
