DESCRIPTION

FEATURES

•

Two guaranteed 150 mA outputs

Designed to operate with ceramic capacitors

Fixed or adjustable outputs

Very small external components

Low 75µV_RMSoutput noise

Very low supply currents

Thermal overload protection

Reverse battery protection

The SC1456 contains two low dropout linear regulators

that operate from a +2.5V to +6V input range and

deliver up to 150mA. PMOS pass transistors allow a

low 110µA supply current per device to remain

independent of load, making these devices ideal for

battery operated portable equipment such as cellular

phones, cordless phones and personal digital

assistants.

Individual low power shutdown

Surface mount packaging (10 pin MSOP)

Full industrial temperature range

Each device can be powered from a separate supply

voltage or the same supply voltage for maximum

flexibility. The output voltage of each device can be

preset or adjusted with an external resistor divider.

Other features include independant low powered

shutdown, short circuit protection, thermal shutdown

protection and reverse battery protection for each

regulator. The SC1456 comes in the tiny 10 lead MSOP

package.
