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.
