Description
The PT7M8202 series are highly accurate, low dropout
voltage regulators with low noise, high ripple rejection
and low current consumption for portable RF and
wireless applications.
The PT7M8202 includes a reference voltage source, an
error amplifier, a driver transistor, a current limit
protection，a thermal protection and an internal phase
compensator.
A noise bypass pin is available for further reduction of
output noise.
The output voltage for the regulator is set by factory
trimming within a range of 1.2V to 3.3V in 100mV step
includes 2.85V. The PT7M8202 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

Note:
Stresses greater than those listed under MAXIMUM
RATINGS may cause permanent damage to the
device. This is a stress rating only and functional
operation of the device at these or any other condi-
tions above those indicated in the operational sec-
tions of this specification is not implied. Exposure
to absolute maximum rating conditions for extended
periods may affect reliability.
