data sheet 9 r000026 xc6219 series high speed ldo regulators, low esr cap. compatible, on/off switch operational explanation 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 output voltage at the vout pin is controlled and stabiliz ed by a system of negative feedback. the current limit circuit and short protect circuit oper ate in relation to the level of output current. further, th e ic's internal circuitry can be shutdown via the ce pin's signal. with the xc6219 series, a stable output volt age is achievable even if used with low es r capacitors as a phase compensation circ uit 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 (vout) and the vss 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. the xc6219 series includes a combination of a fixed current limit er circuit & a foldback circuit, which aid the operations of t he current limiter and circuit protection. when the load current reaches the current limit le vel, the fixed current limiter circuit operates and output voltag e drops. as a result of this drop in output voltage, the foldback circuit operates, output voltage drop s further and output current decreases. when the output pin i s shorted, a current of about 50ma flows. the ic's internal circuitry can be shutdown via the signal from the ce pin with the xc6219 series. in shutdown mode, output at the vout pin will be pulled down to the vss level via r1 & r2. the operational logic of t he ic's ce pin is selectable (pl ease refer to the selection guide on page 2). note that as the standard xc6219b type's regulator 1 and 2 are both ' 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 in crease when the ic is in operation. we suggest that you use this ic with either a vin voltage or a vss voltage input at the ce pin. if this ic is used with the cor rect specifications for the ce pin, the operational logic is fixed and the ic will operate normally. ho wever, supply current may increase as a result of through cu rrent in the ic's internal circuitry. notes on use 1. please use this ic within the stated abs olute maximum ratings. the ic is liable to malfunction should the ratings be exceed ed. 2. where wiring impedance is high, operati ons may become unstable due to noise and/ or phase lag depending on output current. p lease keep the resistance low between vin and vss wiring in particular. 3. please wire the input capacitor (cin) and the output capacitor (cl) as close to the ic as possible. current limit on/off control voltage reference each circuit ce v ss v out v in r2 r1
