ELM86xxxxBxA CMOS Dual ma LDO Regulator General description ELM86xxxxBxA is dual CMOS Voltage Regulator which consists of large current LDOs. With the chip enable function of each channel, it is possible to control on/off independently. This chip enable control is managed by positive logic. The standby current is designed to be Typ..μA. ELM86 series is available only in SOT-6 PKG, while the output voltage is fixed within the range of. to.v. The internal short protection function will limit output current when VOUT pin is in short condition; meanwhile, thermal protection circuit will shut off the output voltage and current when an unusual high chip temperature is detected. Features Output voltage range Input-output voltage difference Standby current consumption Current consumption Input stability Load stability Accuracy of output voltage Short circuit current limiter Thermal shutdown protection Package :.V to.v (by.v) : Typ.mV(Vout=.V, Iout=mA) : Typ..μA : Typ.5μA : Typ..%/V(Iout=mA) : Typ.5mV(mA Iout ma) : ±.%(Vout>.5V), ±mv(vout.5v) : Typ.mA(Vout=V) : Typ.65 C : SOT-6 Application Portable electronics Wireless devices Cell phones Battery-operated devices Maximum absolute ratings Parameter Symbol Limit Unit Input voltage Vin Vss-. to.
