The LP15R100S with Switching Controllers SOP-8L RoHS manufactured by Chip Hope is a Switcher LDO Controller integrated circuit intended for use in the power supply. It is a one-cell management device with an integrated MOSFET for use with 3V and 5V single-cell Lithium-Ion/ Polymer battery applications. The device comes with a wide range of features such as: fast transient response, voltage regulation accuracy ±1.5%, Output current up to 4A, Load switches with an Rds(ON) between 0.9 and 12m in low power mode, low quiescent current of 500uA, and RoHS compliant. The LP15R100S also offers protection against over-voltage, under-voltage, over-current, over-temperature, and short-circuit.
