ΟΟΟ
The BAΟΟΟLBSG (the “ΟΟΟ” 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 characteristics, and is ideal for cellular telephones and other.
!Applications
Residential / industrial device power supplies for cellular telephone such as the CDMA and GSM, and for other portable.
!Features
1) Internal output transistor (I
O
=150mA)
2) Internal temperature protection circuit
3) Power-saving function enables designs with low current 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 I
O
=50mA)
