150ma rf uldo regulator AP2201 preliminary datasheet 1 jun. 2005 rev. 1. 0 bcd semiconductor manufacturing limited sot-23-5 figure 2. package type of AP2201 figure 1. typical application of AP2201 general description the AP2201 is a 150ma output current fixed voltage regulator designed to provide very low noise (45 vrms at 80hz-100khz), ultra low dropout voltage (typically 165mv at 150ma), very low quiescent current (1 a maximum) and excellent power supply ripple rejection (psrr 75db at 100hz) in battery powered applica- tions, such as handsets and pdas and in noise sensitive applications, such as rf electronics. the AP2201 also features individual logic compatible enable/shutdown control inputs, a low power shutdown mode for extended battery life, over current protection, over temperature protection, as well as reversed-bat- tery protection. the output capacitor of 1.0 f minimum and 2.2 f minimum near its pin are recommended when c byp is not used and when c byp is 470pf respectively. the output capacitor should have 5 ? or less esr, tantalum or aluminium electrolytic capacitors are adequate. bypass capacitor is connected to the internal voltage reference to quiet noise. its recommended value is from 470pf to 1nf. if output noise is not a major con- cern and rapid turn-on is necessary, omit c byp and leave byp open. the AP2201 has 2.6v, 2.8v and 3.0v versions now. the AP2201 is available in space saving 5-pin sot- 23-5 package. features up to 150ma regulator output low quiescent current low dropout voltage: v d =165mv at 150ma high precision output voltage: 1% output noise: 45 vrms at 80hz-100khz good ripple rejection ability: 75db at 100hz and i out =100 a tight load and line regulation low temperature coefficient over current protection thermal protection reverse-battery protection zero off-mode current logic-controlled enable applications cellular phones cordless phones digital still cameras wireless communicators pdas / palmtops pc mother board consumer electronics byp c byp 470pf en gnd v out c out + v in AP2201-2.8 v in =3.8v v out =2.8v v out v in 2.2 f c in 1.0 f tantalum

150ma rf uldo regulator AP2201 preliminary datasheet 10 jun. 2005 rev. 1. 0 bcd semiconductor manufacturing limited application information external capacitors the AP2201 requires external capacitors for regula- tor stability. these capacitors must be correctly selected for good performance. input capacitor if there is more than 10 inches of wire between the input and the ac filter or if a battery is used as the input, at least a 1 f capacitor should be placed from in to gnd. output capacitor it is required to prevent oscillation. 1.0 f minimum is recommended when c byp is not used. 2.2 f mini- mum is recommended when c byp is 470pf. the out- put capacitor may be increased without limit for large values to improve transient response. the output capacitor should have an esr of about 5 ? or less. in most cases, tantalum or aluminium electrolytic capacitors are adequate. noise bypass capacitor bypass capacitor is connected to the internal voltage reference. a 680pf capacitor connected from byp to gnd make this reference quiet, resulting in a significant reduction in output noise. when using c byp , output capacitors of 2.2 f or greater are required for better stability. the start-up speed of the AP2201 is inversely proportional to the value of reference bypass capacitor. in some cases if output noise is not a major concern and rapid turn-on is necessary, omit c byp and leave byp open.
