General Description
The MAX8887/MAX8888 low-dropout linear regulators
operate from a +2.5V to +5.5V input and deliver up to
300mA continuous (500mA pulsed) current. The
MAX8887 is optimized for low-noise operation, while the
MAX8888 includes an open-drain POK ouput flag. Both
regulators feature exceptionally low 100mV dropout at
200mA. These devices are available in a variety of pre-
set output voltages in the +1.5V to +3.3V range.
An internal PMOS pass transistor allows the low 55A
supply current to remain independent of load, making
these devices ideal for portable battery-powered equip-
ment such as personal digital assistants (PDAs), cellu-
lar phones, cordless phones, and notebook computers.
Other features include a micropower shutdown mode,
short-circuit protection, thermal shutdown protection,
and an active-low open-drain power-OK (POK) output
that indicates when the output is out of regulation. The
MAX8887/MAX8888 are available in a thin 5-pin SOT23
package that is only 1mm high.
