Overview

Regulator IC BAΟΟΟLBSG series Super-mini package regulator IC BAΟΟΟLBSG series 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 (IO=150mA) 2) Internal temperature protection circuit 3) Power-saving function enables designs with low current consumption 4) High level of ripple rejection (R.
