MAXIM INTEGRATED / ANALOG DEVICES MAX8888EZK33T Low Dropout Voltage Regulator
The MAX8888EZK33+T is a low dropout linear voltage regulator in a 5-pin TSOT-23 package. It operates from a 2.5V to 5.5V input and provides a continuous output current of up to 300mA, with pulsed capabilities up to 500mA. The regulator features an open-drain power-OK (POK) output flag, a low 100mV dropout at 200mA load, and an internally regulated 3.3V output. Its internal PMOS pass transistor ensures a low supply current of approximately 55µA independent of load. The device includes a micropower shutdown mode, short circuit protection, thermal shutdown, and an active-low open-drain POK indicator to signal when the output is out of regulation. It offers a PSRR of 60dB at 1kHz and operates within a temperature range of -40°C to 85°C. Additional features include foldback current limiting and a shutdown supply current of just 0.1µA. This regulator is suited for portable, battery-powered devices such as PDAs, cell phones, cordless phones, and notebooks.
