Low-Dropout, 300mA Linear Regulators in SOT23
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 55µA
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.
