Maxim MAX8940EXK28+

正6V120mA

Overview

The MAX8940EXK28+T low-noise, low-dropout (LDO) linear regulator is designed to deliver up to 120mA continuous output current. This regulator achieves a low 120mV dropout for 120mA load current. The MAX8940EXK28+T uses an advanced architecture to achieve low output voltage noise of 25μVRMS and PSRR of 45dB at 100kHz. The MAX8940EXK28+T is preset to either 2.8V or 3.0V. Designed with a p-channel MOSFET series pass transistor, the MAX8940EXK28+T maintain very low ground current (40μA). The regulator is designed and optimized to work with low-value, low-cost ceramic capacitors. The MAX8940EXK28+T requires only 1μF (typ) of output capacitance for stability with any load. When disabled, current consumption drops to below 1μA. Package is a 5-pin SC70.
