1 / 13 page  1/13 August 2004 s OUTPUT CURRENT 1 UP TO 500mA s OUTPUT CURRENT 2 UP TO 1.0A s LOW DROPOUT VOLTAGE 1 (0.3V @ IO =500mA) s LOW DROPOUT VOLTAGE 2 (0.4V @ IO =1A) s VERY LOW SUPPLY CURRENT (TYP.50µA IN OFF MODE, 1.6mA MAX IN ON MODE) s LOGIC-CONTROLLED ELECTRONIC SHUTDOWN s OUTPUT VOLTAGE AVAILABILITY FOR EACH REGULATOR: 1.8V, 2.5V, 3.3V s INTERNAL CURRENT AND THERMAL LIMIT s STABLE WITH LOW VALUE (MIN 4.7µF) AND LOW E.S.R. OUTPUT CAPACITORS s SUPPLY VOLTAGE REJECTION: 70dB (TYP.) s TEMPERATURE RANGE (-40°C TO 125°C) DESCRIPTION The LDRxxyy is a Very Low Drop Dual Voltage Regulator available in PPAK for the version without inhibit and in SPAK-7L for the version with the shutdown feature. The very low drop-voltage (0.5V) and the very low supply current make it particularly suitable for low noise and low power applications such as PDA, MICRODRIVE and other data storage applications while the used high voltage technology makes this device suitable for consumer applications such as MONITORS AND SET-TOP-BOX. For each VO a Shutdown Logic Control function is available (TTL compatible) to decrease the total power consumption.
