DESCRIPTION
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.
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.
