ELM86xxxxBxA
Dual 400mA LDO Regulator
■General description
ELM86xxxxBxA is dual CMOS Voltage Regulator which consists of 2 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.0.1μA. ELM86 series is available only
in SOT-26 PKG, while the output voltage is fixed within the range of 1.2 to 4.0V. 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.
