3 / 8 page UR5515 CMOS IC UNISONICTECHNOLOGIESCO.,LTD 3 of 8 www.unisonic.com.tw QW-R502-056,A ABSOLUTE MAXIMUM RATINGS PARAMETER SYMBOL RATINGS UNIT Input Voltage VIN 7 V Power Dissipation PD Internally Limited W Junction Temperature TJ 125 ℃ Storage Temperature Range TSTG -40 ~ 150 ℃ Note:1.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. 2.The device is guaranteed to meet performance specification within 0℃~70℃ operating temperature range and assured by design from –20℃~85℃. ELECTRICAL CHARACTERISTICS (Ta = 25℃, unless otherwise specified: VIN = 2.5V, VCNTL= 3.3V, VREF = 1.25V, COUT=10µF(Ceramic).)

For safely operate your system, the 3.3V rail have to be tied to VCNTL rather than 5V rail 2. Keep VCNTL≥VIN on operation power on and power off sequences. 3. VOS offset is the voltage measurement defined as VOUT subtracted from VREF. THERMAL DATA PARAMETER SYMBOL RATINGS UNIT SOP-8 35 TO-252-5 8 Thermal Resistance Junction-Case TO-263-5 θJC 4 ℃ /W |
