CMOS LDO Regulator Series for Portable Equipments High-speed Load Response FULL CMOS LDO Regulators BU TA2WNVX Series, BUTA2WHFV Series ●Description BU □□TA2WNVX /HFV series is high-performance FULL CMOS regulator with 200-mA output, which is mounted on microminiature package SSON004X1216 (1.2 mm 1.6 mm 0.6 mm) &HVSOF5(1.6mm X 1.6mm X0.6mm). It has excellent noise characteristics and load responsiveness characteristics despite its low circuit current consumption of 40 A. It is most appropriate for various applications such as power supplies for logic IC, RF, and camera modules. Microminiature package SSON004X1216 & HVSOF5 with built-in heatsink is adopted for the package, which contributes to the space-saving design of the set. ●Features 1) High-accuracy output voltage of 1% (25 mV on 1.5-V & 1.8-V products) 2) High ripple rejection: 70 dB (Typ., 1 kHz, VOUT 1.8 V)) 3) Compatible with small ceramic capacitor (CIN=Co=1.0 F) 4) Low current consumption: 40 A 5) ON/OFF control of output voltage 6) With built-in overcurrent protection circuit and overheat protection circuit 7) With built-in output discharge circuit 8) Adopting microminiature power package SSON004X1216 ●Applications Battery-powered portable equipment, etc. Absolute maximum rating Parameter Symbol Limits Unit Maximum applied power voltage VMAX -0.3 ~ +6.5 V Power dissipation Pd1 220* 1 (SSON004X1216) mW Pd2 410* 2 (HVSOF5) mW Maximum junction temperature TjMAX +125 °C Operational temperature range Topr -40 ~ +85 °C Storage temperature range Tstg -55 ~ +125 °C *1 When 1 PCB (70 mm 70 mm, thickness 1.6-mm glass epoxy) a standard ROHM board is implemented. Reduced to 2.2 mW/ C when used at Ta=25C or higher. *2 When 1 PCB (70 mm 70 mm, thickness 1.6-mm glass epoxy) a standard ROHM board is implemented. Reduced to 4.1 mW/ C when used at Ta=25C or higher. Recommended operating range (Do not exceed Pd.) Parameter Symbol Limits Unit Input power supply voltage VIN 2.5 ~ 5.5 V Maximum output current IMAX 200 mA Recommended operating conditions Parameter Symbol Min. Typ. Max. Unit Conditions Input capacitor CIN 0.5* 3 1.0 - μF A ceramic capacitor is recommended. Output capacitor CO 0.5* 3 1.0 - μF A ceramic capacitor is recommended. *3 Set the capacity value of the capacitor so that it does not fall below the minimum value, taking temperature characteristics, DC device characteristics, and change with time into consideration.
