• Manufacturer Part Number: max8875euk50t
• Description: Max8875 150ma, Low-dropout Linear Regulator With Power Ok Output
• Manufacturer: Maxim Integrated Products, Inc.

The MAX8875 is designed to deliver low dropout voltages
and low quiescent currents in battery-powered systems.
Power-supply rejection is 60dB at low frequencies. See
the Power-Supply Rejection Ratio vs. Frequency graph in
the Typical Operating Characteristics.
Improve supply-noise rejection and transient response
by increasing the values of the input and output bypass
capacitors. The Typical Operating Characteristics show
the MAX8875’s line- and load-transient responses.
For versions with the output voltage greater than the
minimum input voltage (2.5V), the regulator’s minimum
input-output voltage differential (or dropout voltage)
determines the lowest usable supply voltage. In battery-
powered systems, this will determine the useful end-of-
life battery voltage. Because the MAX8875 uses a
P-channel MOSFET pass transistor, its dropout voltage
is a function of drain-to-source on-resistance (R
multiplied by the load current (see Typical Operating
Characteristics):
