BU30TA2WHFV-TR

CMOS LDO Regulator Series for Portable Equipments High-speed Load Response FULL CMOS LDO Regulators BUTA2WNVX Series, BUTA2WHFV Series No.09020EAT01 ●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 Maximum applied power voltage Power dissipation Maximum junction temperature Operational temperature range Storage temperature range Symbol VMAX Pd1 Pd2 TjMAX Topr Tstg Limits -0.3 ~ +6.5 220*1 (SSON004X1216) 410*2 (HVSOF5) +125 -40 ~ +85 -55 ~ +125 Unit V mW mW °C °C °C *1 When 1 PCB (70 mm  70 mm, thickness 1.6-mm glass epoxy) a standard ROHM board is implemented.
