Regulator ICs Super-mini package regulator IC BALBSG series The BALBSG (the “” 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 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 Io = 50mA) Super-mini regulator lineup Absolute maximum ratings (Ta = 25°C) Recommended operating conditions (Ta = 25°C) 381 Regulator ICs Block diagram 382 BALBSG series Regulator ICs BALBSG series Pin descriptions Input / output circuits 383 Regulator ICs Electrical characteristics BA028LBSG (unless otherwise noted, Ta = 25°C, VCC = 3.8V) 384 BALBSG series Regulator ICs BALBSG series BA030LBSG (unless otherwise noted, Ta = 25°C, VCC = 4.0V) 385 Regulator ICs BA032LBSG (unless otherwise noted, Ta = 25°C, VCC = 4.2V) 386 BALBSG series Regulator ICs BALBSG series BA038LBSG (unless otherwise noted, Ta = 25°C, VCC = 4.8V) 387 Regulator ICs Application example Electrical characteristic curves (BA030LBSG) 388 BALBSG series Regulator ICs BALBSG series External dimensions (Units: mm) 389
