da9333.001 29 january 2004 1 (11) this is preliminary information on a new product under development. micro analog systems reserves the right to make any changes without notice. mas9333 150 ma ldo voltage regulator ic ? high psrr still when v in is only v out(nom) + 0.5 v ? low noise, 40 vrms, without external bypass capacitor ? fast start-up time: 21 s ? low dropout: 124 mv @ 150 ma ? low minimum output capacitance requirement: 0.23 f ? stable with low-esr output capacitors description mas9333 is a low dropout voltage regulator, which offers good performance even at low v in voltage. the output noise level of mas9333 is 40 vrms without an external bypass capacitor. mas9333 features very fast start-up time (typically only 21 s from start-up to within 1% of v out(nom) ) and low dropout voltage ( 124 mv typical at 150 ma). also it has a ripple reje ction ability of 53 db at 10 khz even when v in = v out(nom) + 0.5 v. the very short start-up time of mas9333 combined with good performance offers an opportunity to switch the regulator off and on even in timing critical and/or noise sensitive applications. the equivalent series resistance (esr) range of output capacitors that can be used with mas9333 is very wide. this esr range from a few m ? up to a couple of ohms combined with no minimum output current requirement makes the usage of mas9333 easier and low in cost. in order to save power the regulator goes into sleep mode when it is disabled. mas9333 also includes an auto-discharge function, wherein a shutdown transistor turns on and discharges the output capacitor when mas9333 is disabled. an internal thermal protection circuit prevents the device from overheating. also the maximum output current is internally limited. features applications ? good performance at low v in voltage ? pin compatible with lp2985/lp3985 ? integrated bypass capacitor ? auto-discharge function ? internal thermal shutdown ? short circuit protection ? tsot 5 or wl-csp package ? several output voltage options available, see ordering information p.10 ? cellular phones ? cordless phones ? accessories ? wireless systems ? battery powered systems ? portable systems ? radio control systems ? low voltage systems
