MIC2920X 400 mA Low Dropout Regulators Features General Description High Output Voltage Accuracy The MIC2920 family (MIC2920A, MIC29201, MIC29202, and MIC29204) are efficient voltage Ensured 400 mA Output regulators with very low dropout voltage (typically Low Quiescent Current 40 mV at light loads and 370 mV at 250 mA) and very Low Dropout Voltage low quiescent current (140 A typical). The quiescent Extremely Tight Load and Line Regulation current of the MIC2920A increases only slightly in Very Low Temperature Coefficient dropout, prolonging battery life. Key MIC2920A features include protection against reversed battery, Current and Thermal Limiting fold-back current limiting, and automotive load dump Input Withstands 20V Reverse Battery and +60V protection (60V positive transient). Positive Transients The MIC2920 family of devices are available in several Error Flag Warns of Output Dropout configurations. The MIC2920A-x.x devices are 3-lead Logic-Controlled Electronic Shutdown fixed-voltage regulators available in 3.3V, 4.85V, 5V, Output Programmable from 1.24V to 26V and 12V outputs. The MIC29201 is a fixed-voltage (MIC29202/MIC29204) regulator that offers a logic-compatible ON/OFF Available in TO-220-3, TO-220-5, and (shutdown) input and an error flag output. This flag may Surface-Mount TO-263-5, SOT-223, and SOIC-8 also be used as a power-on reset signal. A Packages logic-compatible shutdown input is provided on the adjustable MIC29202, which allows the regulator to be Applications switched on and off. The MIC29204 8-lead SOIC Battery-Powered Equipment adjustable regulator includes both shutdown and error Cellular Telephones flag pins and may be pin-strapped for 5V output or Laptop, Notebook, and Palmtop Computers programmed from 1.24V to 26V using two external resistors.
