FULL CMOS LDO Regulators
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, VOUT1.8 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

About input/output capacitor
It is recommended to place a capacitor as close as possible to the pins
between the input terminal and GND or between the output terminal and
GND.
The capacitor between the input terminal and GND becomes valid when
source impedance increases or when wiring is long. The larger the
capacity of the output capacitor between the output terminal and GND is,
the better the stability and characteristics in output load fluctuation become.
However, please check the status of actual implementation. Ceramic
capacitors generally have variation, temperature characteristics, and direct
current bias characteristics and the capacity value also decreases with
time depending on the usage conditions. It is recommended to select a
ceramic capacitor upon inquiring about detailed data of the related
manufacturer.
About the equivalent series resistance (ESR) of a ceramic capacitor
Capacitors generally have ESR (equivalent series resistance) and it
operates stably in the ESR-IOUT area shown on the right. Since ceramic
capacitors, tantalum capacitors, electrolytic capacitors, etc. generally have
different ESR, please check the ESR of the capacitor to be used and use it
within the stability area range shown in the right graph for evaluation of the
actual application.
