Low-Dropout, 300mA Linear Regulators in SOT23

7/MAX8

General Description

Features

♦ Guaranteed 300mA Output Current (500mA for

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 power-OK (POK) ouput

flag. Both regulators feature exceptionally low 100mV

dropout at 200mA. These devices are available in a vari-

ety of preset output voltages in the 1.5V to 3.3V range.

Pulsed Loads)

♦ Low 100mV Dropout at 200mA Load

♦ POK Output (MAX8888)

♦ 42µV

Output Noise (MAX8887)

RMS

♦ Preset Output Voltages (1.5V, 1.8V, 2.85V, and

3.3V)

♦ 55µA No-Load Supply Current

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 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.

♦ Thermal-Overload and Short-Circuit Protection

♦ Foldback Output Current-Limit Protection

♦ 60dB PSRR at 1kHz

♦ 0.1µA Shutdown Current

♦ Thin 5-Pin SOT23 Package, 1mm High
