CMOS LDO Regulators for Portable Equipments 1ch 200mA CMOS LDO Regulators BU TA2WNVX series, BUTA2WHFV series No.11020ECT01 Description BUTA2WNVX /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 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. Line up 200 mA BUTA2WNVX / 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 BUTA2WNVX SSON004X1216 BUTA2WHFV HVSOF5 Model name: BHTA2W a b Symbol Contents Specification of output voltage Output voltage (V) Output voltage (V) Output voltage (V) 15 1.5V(Typ.) 28 2.8V(Typ.) 32 3.2V(Typ.) a 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.) - - NVX :SSON004X1216 b Package HFV :HVSOF5 www.rohm.com 2011.01 - Rev.C 1/29 2011 ROHM Co., Ltd.
