" operational explanation output voltage control with the xc6204 series : low esr capacitors with the xc6204 series, a stable output voltage is achievable even if used with low esr capacitors as a phase compensation circuit is built-in. in order to ensure the effectiveness of the phase compensation, we suggest that an output capacitor (cl) is connected as close as possible to the output pin (v out ) and the v ss pin. please use an output capacitor with a capacitance value of at least 1 f. also, please connect an input capacitor (cin) of 0.1 f between the vin pin and the vss pin in order to ensure a stable power input. current limiter, short-circuit protection the xc6204 series includes a combination of a fixed current limiter circuit & a foldback circuit which aid the operations of th e current limiter and circuit protection. when the load current reaches the current limit level, the fixed current limiter circui t operates and output voltage drops. as a result of this drop in output voltage, the foldback circuit operates, output voltage drops furth er and output current decreases (refer to the data on page 5). when the output pin is shorted, a current of about 60ma flows. ce pin the ic's internal circuitry can be shutdown via the signal from the ce pin with the xc6204 series. in shutdown mode, output at the v out pin will be pulled down to the vss level via r1 & r2. the operational logic of the ic's ce pin is selectable (please refer to the selection guide on page 2). note that as the standard xc6204b type is ' high active/no pull down' , operations will become unstable with the ce pin open. although the ce pin is equal to an inverter input with cmos hysteresis, with either the pull-up or pull-down options, the ce pin input current will increase when the ic is in operation. we suggest that you use this ic with either a v in voltage or a v ss voltage input at the ce pin. if this ic is used with the correct specifications for the ce pin, the ic will operatenormally. however, supply current may increase as a result of through current in the ic's internal circuitry if a voltage between 0.25v and 1.5v is input. " notes on use 1. please use this ic within the stated absolute maximum ratings. the ic is liable to malfunction should the ratings be exceede d. 2. where wiring impedence is high, operations may become unstable due to noise and/or phase lag depending on output current. please strengthen v in and v ss wiring in particular. 3. please wire the input capacitor (c in ) and the output capacitor (c l ) as close to the ic as possible. high speed ldo regulators xc6204 series current limit on/off control voltage reference each circuit ce v ss v out v in r2 r1 the voltage divided by resistors r1 & r2 is compared with the internal reference voltage by the error amplifier. the p-channel mosfet, which is connected to the vout pin, is then driven by the subsequent output signal. the ouput voltage at the vout pin is controlled & stabilised by a system of negative feedback. the current limit circuit and short protect circuit operate in relation to the level of output current. further, the ic's internal circuitry can be shutdown via the ce pin's signal. 0.01 0.1 1 10 100 0 20406080100 io u t(m a ) esr( ) topr=25 o c vin=~10v,vout=1.8~6.0v cin=1.0uf(ceram ic),cl=1.0uf(ceram ic) stable region 6
