... RMS 150mA. The output voltage is preset to voltages in the range of 2.5V to 5.0V, in 100mV increments. The MAX8867 and MAX8868 are pin-compatible with the MAX8863 and MAX8864, except for the BP pin. Designed with an internal P-channel MOSFET pass transistor, the MAX8867/MAX8868 maintain a low 100µ ...

... Linear Regulators in SOT23 ______________________________________________________________Pin Description PIN NAME Active-Low Shutdown Input. A logic low reduces the supply current to 10nA. On the MAX8868, a logic low SHDN 1 also causes the output voltage to discharge to GND. Connect to IN for normal operation. Ground. This pin also functions as a heatsink. Solder to a large pad or the circuit-board ground plane to ...

... Output Noise Spectral Density. __________Applications Information Normally, use a 1µF capacitor on the MAX8867/ MAX8868’s input and a 1µF to 10µF capacitor on the output. Larger input capacitor values and lower ESRs provide better supply-noise rejection and line-transient response. Reduce noise and improve load-transient response, stability, and power-supply rejection by using large output capacitors ...

... Shutdown Exit Delay graph in the Typical Operating Characteristics ). PSRR and Operation from Sources Other than Batteries The MAX8867/MAX8868 are designed to deliver low dropout voltages and low quiescent currents in battery- powered systems. Power-supply rejection is 63dB at low frequencies and rolls off above 10kHz. See the Power-Supply Rejection Ratio Frequency graph in the Typical Operating Characteristics ...
