1/25 XC6227 series 700ma high speed ldo regulator with reverse current protection general description the XC6227 series is a highly accurate, low noise, high ripple rejection, low dropout, and low power consumption high speed voltage regulator. the series consists of a voltage reference, an error amplifier, a driver transistor, a current limiter, a thermal protection ci rcuit, a reverse current protection circuit and a phase compensation circuit. the ce function enables the entire circuit to be placed in a stand-by state by inputting a low level signal to the ce pin. over-current protection and thermal protecti on circuits are integrated. the protection circuit starts to operate when either ou tput current reaches the current limit level or junction temperature reaches the tem perature limit. with t he reverse current protec tion function of a driver transistor, the reve rse current flow is prohibited when v out voltage is higher than v in voltage. for an example, when a battery is connected to the v out pin, battery current will not flow back to the XC6227. features maximum output current : 700ma dropout voltage : 120mv @i out =300ma(v out =3.0v) operating voltage range : 1.7v ~ 6.0v output voltages : 0.8v~5.0v (0.05v increments) accuracy : + 1% (v out 2.0v) + 0.02v (v out Q 2.0v) low power consumption : 100 a chip enable(ce) : active high standby current below 0.1 a high ripple rejection : 65db @ 1khz operating ambient temperature : -40 ~+85 low esr capacitor : ceramic capacitor packages : usp-6c, sot-25, sot-89-5 environmentally friendly : eu rohs compliant, pb free typical application circuit etr0354-003 a pplications usb products and hdmi equipments electronic dictionaries mobile phones portable game consoles camera modules rv out ?-?R v out =3.3v i out =0ma XC6227c331 -2 0 2 4 6 8 10 00.511.522.533.544.555.56 input voltagev in (v) v out sink currenti revs (a) -40 25 85 typical performance characteristics v out sink current vs. input voltage

7/25 XC6227 series operational explanation the voltage divided by two resistors r1 and r2 is compared with the internal reference voltage by the error amplifier. the p-channel mosfet connected to the v out pin, is then driven by the subsequent out put signal. the output voltage at the v out pin is controlled and stabilized by a system of negative feedback. the current limit and short pr otection operate in relation t o the level of output current. the thermal pr otection operates in relation to the leve l of heat generation. the reverse current protection operates when v out voltage is higher than v in voltage. further, the ic's internal circuitry can be turned off via the ce pin's signal. the XC6227 needs an output capacitor c l for phase compensation. values required for the phase compensation are shown in the chart below. if a loss of the capacitance happens, st able phase compensation may not be obtained. please ensure to use a capacitor which does not depend on bias or temperature too much. for a stable power input, please connect an input capacitor c in of 1.0 f between the v in pin and the v ss pin. output voltage (v) output capacitor value 0.8v 2.05v c l =6.8 f (min.) 2.1v 2.45v c l =4.7 f (min.) 2.5v 5.0v c l =2.2 f (min.) the XC6227 series includes reverse current protection to prevent the damage as a result of current flow from v out pin to the v in pin and v ss pin when the power supply is connected to the v out pin. when v in is smaller than v out, the reverse current protection works and suppress the reverse current to 1.5 a (max.). when v in is smaller than v out , the v out pin sink current flowing from the v out pin to the v ss pin is 2.8 a (typ.) as the ic operation current. please also note when an external power supply is connected to the v out pin, please use it within 6.0v. the XC6227 series integrates an output curr ent limiter and a fold-back short protec tion for the output pin. when the load current reaches the current limit level, the fixed current limiter circuit operates and output voltage drops. when the output p in is short-circuited to the v ss pin, the current is decreased to a level of 55ma (typ.). when the junction temperature of t he built-in driver transistor reache s the temperature limit level (150 typ.), the thermal shutdown circuit operates and the driver transistor will be turned off. the ic resumes its operation when the thermal shutdown function is released and the ic?s operation is auto matically restored because the junction temperature drops to the level of 125 (typ.) as the thermal shutdown release voltage. output capacitor (c l ) table
8/25 XC6227 series operational explanation (continued) the entire XC6227 circuitry can be turned off via the ce pin signal. in shutdown mode, output at the v out pin will be pulled down to the v ss level via r1 & r2. the XC6227c series has a pull-down resistor in order to operate normally even the ce pin is left open (when the ce pin is left open, the ic stops operation), so t hat the ce pin input current flows. if the ce pin voltage is set with the specified voltage range, the logic is fixed and the ic will operate normally. however, t he supply current may increase as a result of shoot-through current in the ic's internal circuitry when a medium voltage is input to the ce pin. notes on use 1. for temporary, transitional voltage drop or voltage rising phe nomenon, the ic is liable to malfunction should the ratings be exceeded. 2. where wiring impedance is high, o perations may become unstable due to noise and/or phase lag depending on output current. please wire the input capacitor (c in ) and the output capacitor (c l ) as close to the ic as possible. 3. torex places an importance on improv ing our products and its reliability. however, by any possibility, we would request user fa il-safe design and post-aging tr eatment on system or equipment.
