CMOS LDO Regulator Series for Portable Equipments
High-speed
Load Response
FULL 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 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.
