SC1456

Dual 150mA Ultra Low

Dropout, Low Noise Regulator

POWER MANAGEMENT

Description

Features

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.

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

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 (lead

free, fully WEEE and RoHS compliant available).

Individual low power shutdown

Full industrial temperature range

Surface mount packaging (10 pin MSOP)
