CMOS LDO Regulators for Portable Equipments

1ch 200mA

CMOS LDO Regulators

BUTA2WNVX series, BUTA2WHFV 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  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))

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.
