POWER MANAGEMENT Description
The SC1453 is a low dropout linear
regulator that operates from a +2.
5V to +6.
5V input range and delivers up to 150mA.
A PMOS pass
transistor allows the low 75µA supply current to remain independent of load, making these devices ideal for battery operated portable equipment such as cellular phones, cordless phones and personal digital assistants.
150mA Ultra Low Dropout
Regulator with Low Noise Bypass
