CMOS LDO Regulators for Portable Equipments
1ch 200mA
CMOS LDO Regulators
BUTA2WNVX series, BUTA2WHFV 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, VOUT1.8 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.
