BU34TA2WNVX-TR

CMOS LDO Regulators for Portable Equipments 1ch 200mA CMOS LDO Regulators BUTA2WNVX series, BUTA2WHFV series No.11020ECT01 ●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  1.6mm  0.6mm). It has excellent noise characteristics and load responsiveness characteristics despite its low circuit current consumption of 40 µA. 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 µF) 4) Low current consumption: 40 µA 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. ●Line up ■ 200 mA BU□□TA2WNVX / HFV series Product Name 1.5 1.8 2.5 2.6 2.7 2.8 2.85 2.9 3.0 3.1 3.2 3.3 3.4 Package BU□□TA2WNVX ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ SSON004X1216 BU□□TA2WHFV ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ HVSOF5 Model name: BH□□TA2W□□□ a b Symbol Contents Specification of output voltage a b □□ Output voltage (V) □□ Output voltage (V) □□ Output voltage (V) 15 1.5V(Typ.) 28 2.8V(Typ.) 32 3.2V(Typ.) 18 1.8V(Typ.) 2J 2.85V(Typ.) 33 3.3V(Typ.) 25 2.5V(Typ.) 29 2.9V(Typ.) 34 3.4V(Typ.) 26 2.6V(Typ.) 30 3.0V(Typ.) - - 27 2.7V(Typ.) 31 3.1V(Typ.) - - Package www.rohm.com © 2011 ROHM Co., Ltd.
