Typical output noise for these devices is just 30µVRMS, and typical dropout is only 165mV at 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 tran- sistor, the MAX8867/MAX8868 maintain a low 100µA supply current, independent of the load current and dropout voltage. Other features include a 10nA logic- controlled shutdown mode, short-circuit and thermal- shutdown protection, and reverse battery protection. The MAX8868 also includes an auto-discharge function, which actively discharges the output voltage to ground when the device is placed in shutdown. Both devices come in regular and thin 5-pin SOT23 packages. ________________________Applications Cellular Telephones Modems Cordless Telephones Hand-Held Instruments PCS Telephones Palmtop Computers PCMCIA Cards Electronic Planners ____________________________Features o Low Output Noise: 30µVRMS o Low 55mV Dropout at 50mA Output (165mV at 150mA output) o Low 85µA No-Load Supply Current o Low 100µA Operating Supply Current (Even In Dropout) o Thermal-Overload and Short-Circuit Protection o Reverse Battery Protection o Output Current Limit o Preset Output Voltages (±1.4% Accuracy) o 10nA Logic-Controlled Shutdown Low-Noise, Low-Dropout, 150mA Linear Regulators in SOT23 ________________________________________________________________ Maxim Integrated Products 1 GND OUT IN 15 BP SHDN MAX8867 MAX8868 SOT23-5 TOP VIEW 2 34 __________________Pin Configuration 19-1302; Rev 3; 7/02 MAX8867 MAX8868 INPUT 2.5V TO 6.5V IN OUT SHDN CBP 0.01 µF COUT 1 µF CIN 1 µF OFF ON BP GND OUTPUT PRESET 2.5V TO 5.0V 150mA __________Typical Operating Circuit _________________Ordering Information *Dice are tested at TA = +25°C only. **xy is the output voltage code (see Expanded Ordering Information table at end of data sheet).
