Description
The PT7M8220B series are highly accurate, low dropout
voltage regulators with high current, low noise, high
ripple rejection and low current consumption.
The PT7M8220B includes a reference voltage source, an
error amplifier, a driver transistor, a current limit
protection, a thermal protection and an internal phase
compensator.
The output voltage for the regulator is set by factory
trimming within a range of 1.2V to 3.3V in 100mV step
including 2.85V. The PT7M8220B series are stable with
low ESR ceramic capacitors.
Applications
Mobile phones (PDC, GSM, CDMA, IMT2000 etc.)
Cordless phones and radio communication
Digital still cameras and video cameras
PDAs
MP3 players
Portable devices
