PARAMETER SYMBOL RATINGS UNIT Supply Input Voltage VIN 6 V EN Input Voltage VEN 6 V Power Dissipation (TA = 25°C) PD 0.4 W Junction Temperature TJ 150 °C Storage Temperature TSTG - 65~ +150 °C Note:Absolute maximum ratings are those values beyond which the device could be permanently damaged. Absolute maximum ratings are stress ratings only and functional device operation is not implied. THERMAL DATA PARAMETER SYMBOL RATINGS UNIT Junction to Ambient θJA 250 °C/W OPERATING CONDITIONS PARAMETER SYMBOL RATINGS UNIT Supply Input Voltage VIN 2.2 ~ 5.5 V Junction Temperature TJ -40 ~ +125 °C Ambient Temperature TA -40 ~ +85 °C Note: The device is not guaranteed to function outside its operating conditions.

Regulation is measured at constant junction temperature by using a 2ms current pulse. Devices are tested for load regulation in the load range from 1mA to 500mA. 2. Quiescent, or ground current, is the difference between input and output currents. It is defined by IQ = IIN - IOUT under no load condition (IOUT = 0mA). The total current drawn from the supply is the sum of the load current plus the ground pin current. 3. The dropout voltage is defined as VIN -VOUT, which is measured when VOUT is VOUT(NORMAL)×98%. |
