Super-mini package regulator IC
BA
fff
LBSG series
The BA
fff
LBSG (the "
fff
" indicates the output voltage value) is a low-saturation series regulator IC employing
the super-mini mold package of the SMP5 (2916 package). Equipped with a power-saving function that reduces current
consumption, it also offers outstanding ripple rejection and other characteristics, and is ideal for cellular telephones and
other compact telephones.
Applications
Residential / industrial device power supplies for cellular
telephones such as the CDMA and GSM, and for other
portable communication devices
Features
1) Internal output transistor (Io = 150mA)
2) Internal temperature protection circuit
3) Power-saving function enables designs with low cur-
rent consumption
4) High level of ripple rejection (R.R. = 66dB)
5) SMP5 super-mini package enables space-saving
designs
6) Low I / O voltage differential (90mV Typ. at Io =
50mA)
