Features - Mini 8 MSOP Package - Up to 150 m A per Regulator Output - Low Quiescent Current - Low Dropout Voltage - Wide Selection of Output Voltages - Tight Load and Line Regulation - Low Temperature Coefficient - Current and Thermal Limiting - Reversed Input Polarity Protection - Zero Off-Mode Current - Logic-Controlled Electronic Enable Applications - Cellular Telephones - Laptop, Notebook, and Palmtop puters - Battery-Powered Equipment - Barcode Scanners - SMPS Post-Regulator DC/DC Modules - High-Efficiency Linear Power Supplies General Description The MIC5210 is a dual linear voltage regulator with very low dropout voltage (typically 10 m V at light loads and 140 m V at 100 m A), very low ground current (225 µA at 10 m A output), and better than 1% initial accuracy. It also features individual logic-patible enable/shutdown control inputs. Both regulator outputs can supply up to 150 m A at the same time as long as each regulator’s maximum junction temperature is not exceeded. Key features include a reference bypass pin to improve its already low-noise performance, reversed-battery protection, current limiting, and overtemperature shutdown. Designed especially for hand-held battery powered devices, the MIC5210 can be switched by a CMOS or TTL patible logic signal, or the enable pin can be connected to the supply input for 3-terminal operation. When disabled, power consumption drops nearly to zero. Dropout ground current is minimized to prolong battery life. The MIC5210 is available in 2.7V, 2.8V, 3.0V, 3.3V, 3.6V, 4.0V, and 5.0V fixed voltage configurations. Other voltages are available; contact Microchip for details.
