da9125.004 17 february, 2000 1 mas9125 5 outputs ldo voltage regulator ic ? five low dropout voltage regulators ? enable/disable control pin for each regulator ? common control pin to shutdown the whole circuit ? all outputs ultra low noise ? excellent ripple rejection ? very low quiescent current ? thermal and current limiting protection description the mas9125 is a voltage regulator ic with five 2.8 v ultra low noise ldo regulators. each regulator has its own independent enable/disable control pin. additionally, all the outputs can be turned off by using a common control pin, which overrides regulator specific control pins. the highest output current is 150 ma (for the output 4). mas9125 features a very low quiescent current: max 5 a in off state and 90 a in on state. the dropout voltage is typically 0.11 v for outputs 1, 2, 3, and 5 and 0.17 v for output 4. the regulators 1, 2, and 3 have a common power supply pin marked as vcc_1. vcc_2 functions as a power supply pin for the regulators 4 and 5. mas9125 excels especially in noise performance and ripple rejection. since all the outputs exhibit ultra low noise, noise sensitive circuitry can be driven by any of them. with high ripple rejection, mas9125 effectively shields downstream electronics against power line disturbances. an internal thermal protection circuit prevents the device from overheating. the maximum output current is limited internally, too. features applications ? 2.8 v regulators at 30 ma, 40 ma, 50 ma, 150 ma, and 60 ma ? excellent ripple rejection: 72 db typical at 1 khz, and 52 db typical at 10 khz ? ultra low noise: 21 vrms typical and 30 vrms maximum for all regulators over frequency range 100 hz?100 khz ? fast dynamic response ? output voltage accuracy < 1.7% at 27 o c ? 100 nf for output capacitors 1, 2, 4, and 5 and 1 f for output capacitor 3 ? separate enable/disable control for each output ? common control pin to shutdown the whole ic ? very low quiescent current: maximum 5 a in off state (independent & common controls off), typical 90 a in on state (common control on, independent controls off) ? tssop16 package ? functionally and pin compatible with mc33765 ? mobile phones ? cordless phones ? portable systems ? battery powered systems ? systems needing stabilized power in separate blocks
