ꢀ TAR5S XX Series: Point Regulators
The point regulator series features one or two regulator ICs in a small package. The devices are suitable for
use as power supplies in battery-driven mobile phones and portable audio players.
a) Features
• Small package (SMV: SOT-25 5-pin)
• Drop-out voltage 130 mV (typ.), 200 mV (max) @50 mA
• Connection to a noise bypass capacitor realizes
low noise of 30 µVrms (typ.).
• High performance with ripple rejection of 70 dB (typ.) @f = 1 kHz
• ON/OFF control function (ON at 1.5 V or higher; OFF at 0.4 V or lower)
• Stand-by current 0.1 µ A or lower (when control function is OFF)
• Built-in overtemperature and overcurrent protection circuits

ꢀ Precautions for Use
The noise capacitor should be connected to NOISE pin to GND for stable operation, the recommended value
is higher than 0.0047 µF.
TAR5S XX Series is built-in overtemperature and overcurrent protection circuits, these functions do not restrict
use of the devices within their absolute maximum ratings.
Toshiba recommend that the specific technical data which relates to a product be checked before it is used,
and that products always be used within their absolute maximum ratings.
