MAX8887EZK18+T

The MAX8887EZK18+T is a low dropout, 300mA linear regulator in 5 pin TSOT-23 package. It 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. The regulator feature exceptionally low 100mV dropout at 200mA. This device is available with a preset output voltage of 1.8V. An internal PMOS pass transistor allows the low 55μA supply current to remain independent of load making this device ideal for portable battery powered equipment such as personal digital assistants (PDAs), cellular 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.

• PSRR is 60dB at 1KHz
• Operating temperature range from -40°C to 85°C
• Foldback output current limit protection
• Shutdown supply current is 0.1μA
• No load supply current is 55μA
