UNISONIC TECHNOLOGIES CO., LTD M293010 Preliminary LINEAR INTEGRATED CIRCUIT 1A, LOW-DROPOUT, 1.0~16V REGULATOR DESCRIPTION The UTC M293010 is 1A low dropout liner voltage regulators that provide low voltage and high-current output. Designed especially for the high-current requirements in industrial and consumer applications; embedded core, memory, or logic supplies; TVs, VCRs, and office equipment. The UTC M293010 is an efficient voltage regulator with very low dropout voltage and very low ground current. This device delivers a regulated output at up to 1A. Included overcurrent and thermal protection improve overall system reliability. Devices with fixed output voltages are also available. A inside bandgap reference provides accuracy and excellent temperature characteristics for regulator. IQ does not increase significantly as the dropout voltage is approached, an ideal feature in standby/resume power systems where data integrity is crucial. A inside power pnp provides a dropout voltage of less than 600mV at 1A of current. An LS-TTL/CMOS-compatible input gives the designer complete control over power up, standby, or power down. Low output voltages eliminate the need for expensive PWM buck converters. The low dropout voltage permits more efficient regulation before output regulation is lost. The UTC M293010 provided a 5-lead TO-252 style surface-mount plastic package with ground tab to provide a low-resistance path for maximum heat dissipation.
