Part Manufacturer: Maxim


Part Description: MAX8887 88 DS

Part Details:

19-1859; Rev 3; 11/06 Low-Dropout, 300mA Linear Regulators in SOT23 MAX8887/MAX8888 General Description Features The MAX8887/MAX8888 low-dropout linear regulators Guaranteed 300mA Output Current (500mA for operate from a 2.5V to 5.5V input and deliver up to Pulsed Loads) 300mA continuous (500mA pulsed) current. The Low 100mV Dropout at 200mA Load MAX8887 is optimized for low-noise operation, while theMAX8888 includes an open-drain POK ouput flag. Both POK Output (MAX8888) regulators feature exceptionally low 100mV dropout at 42µVRMS Output Noise (MAX8887) 200mA. These devices are available in a variety of pre- Preset Output Voltages (1.5V, 1.8V, 2.85V, and set output voltages in the 1.5V to 3.3V range. 3.3V) An internal PMOS pass transistor allows the low 55µA 55µA No-Load Supply Current supply current to remain independent of load, makingthese devices ideal for portable battery-powered equip- Thermal Overload and Short-Circuit Protection ment such as personal digital assistants (PDAs), cellu- Foldback Output Current-Limit Protection lar phones, cordless phones, and notebook computers. 60dB PSRR at 1kHz Other features include a micropower shutdown mode,short-circuit protection, thermal shutdown protection, 0.1µA Shutdown Current and an active-low open-drain power-OK (POK) output Thin 5-Pin SOT23 Package, 1mm High that indicates when the output is out of regulation. TheMAX8887/MAX8888 are available in a thin 5-pin SOT23 Ordering Information package that is only 1mm high.
