Low-Dropout, 300mA Linear
Regulators in SOT23
MAX8887/MAX8888
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 preset 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 equipment such as personal di...
