MAX8878EUK33+T

The MAX8878EUK33+T is a low-noise, low-dropout, 150mA linear regulator in 5 pin SOT-23 package. This LDO regulator operates from a 2.5V to 6.5V input and deliver up to 150mA. It is pin-compatible with industry-standard '2982 and offers an improved dropout voltage. Typical output noise is 30µVRMS and typical dropout is only 165mV at 150mA. The output voltage is preset to 3.3V. Designed with an internal P-channel MOSFET pass transistor, MAX8878 maintain a low 100µA supply current, independent of load current and dropout voltage. Other features include a 10nA logic-controlled shutdown mode, short-circuit and thermal shutdown protection and reverse battery protection. It also includes an auto-discharge function which actively discharges output voltage to ground when device is placed in shutdown. It is used in cellular telephones, cordless telephones, PCS telephones, PCMCIA cards, modems, hand-held instruments and computers.

• Low 55mV dropout at 50mA output (165mV at 150mA output)
• Low 85μA no-load supply current
