RT9193 marking information for marking information, contact our sales representative directly or through a richtek distributor located in your area. ordering information general description the RT9193 is designed for portable rf and wireless applications with demanding performance and space requirements. the RT9193 performance is optimized for battery-powered systems to deliver ultra low noise and low quiescent current. a noise bypass pin is available for further reduction of output noise. regulator ground current increases only slightly in dropout, further prolonging the battery life. the RT9193 also works with low-esr ceramic capacitors, reducing the amount of board space necessary for power applications, critical in hand-held wireless devices. the RT9193 consumes less than 0.01 a in shutdown mode and has fast turn-on time less than 50 s. the other features include ultra low dropout voltage, high output accuracy, current limiting protection, and high ripple rejection ratio. available in the sc-70-5, sot-23-5, tsot-23-5, wdfn-6l 2x2 and msop-8 packages. features z z z z z ultra low noise for rf application z z z z z ultra fast response in line/load transient z z z z z quick start-up (typically 50 s) z z z z z <0.01 a standby current when shutdown z z z z z low dropout : 220mv @ 300ma z z z z z wide operating voltage ranges : 2.5v to 5.5v z z z z z ttl-logic-controlled shutdown input z z z z z low temperature coefficient z z z z z current limiting protection z z z z z thermal shutdown protection z z z z z only 1 f output capacitor required for stability z z z z z high power supply rejection ratio z z z z z custom voltage available z z z z z rohs compliant and 100% lead (pb)-free applications z cdma/gsm cellular handsets z battery-powered equipment z laptop, palmtops, notebook computers z hand-held instruments z pcmcia cards z portable information appliances typical application circuit RT9193- package type u5 : sc-70-5 b : sot-23-5 j5 : tsot-23-5 qw : wdfn-6l 2x2 (w-type) f : msop-8 output voltage 15 : 1.5v 16 : 1.6v : 49 : 4.9v 50 : 5.0v 1h : 1.85v 2h : 2.85v 4g : 4.75v (1.5v to 5v with 0.1v step is available) lead plating system p : pb free g : green (halogen free and pb free) vin gnd vout RT9193 c out 1f/x7r c in 1f/x7r v in v out en bp c bp 22nf chip enable (option for low noise) 1 of 4 4008-318-123 sales@twtysemi.com http://www.twtysemi.com product specification
