MIC5210 Dual 150mA LDO Regulator General Description Features The MIC5210 is a dual linear voltage regulator with very Micrel Mini 8 MSOP package low dropout voltage (typically 10mV at light loads and Up to 150mA per regulator output 140mV at 100mA), very low ground current (225A at Low quiescent current 10mA output), and better than 1% initial accuracy. It also Low dropout voltage features individual logic-compatible enable/shutdown control inputs. Wide selection of output voltages Both regulator outputs can supply up to 150mA at the Tight load and line regulation same time as long as each regulators maximum junction Low temperature coefficient temperature is not exceeded. Current and thermal limiting Key features include an undervoltage monitor with an error Reversed input polarity protection flag output, a reference bypass pin to improve its already Zero off-mode current low-noise performance (8-pin versions only), reversed- Logic-controlled electronic enable battery protection, current limiting, and overtemperature shutdown. Designed especially for hand-held battery powered Applications devices, the MIC5210 can be switched by a CMOS or TTL Cellular telephones compatible logic signal, or the enable pin can be connected to the supply input for 3-terminal operation. Laptop, notebook, and palmtop computers When disabled, power consumption drops nearly to zero. Battery-powered equipment Dropout ground current is minimized to prolong battery life. Bar code scanners Key features include current limiting, overtemperature SMPS post-regulator/dc-to-dc modules shutdown, and protection against reversed battery. High-efficiency linear power supplies 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 Micrel for details.
