XC6505 Series ETR0356-003a Low Power Consumption, High Speed 200mA LDO Regulator - 10.5V Input GENERAL DESCRIPTION Even the XC6505 series is a low power consumption such as 5.5A, the IC is a high speed CMOS LDO regulator that features high accurate, low noise, high ripple rejection, and low dropout. The series consists of a voltage reference, an error amplifier, a driver transistor, a current limiter, a phase compensation circuit and a thermal shutdown circuit. The CE function enables the circuit to be in stand-by mode by inputting low level signal. In the stand-by mode, the series enables the electric charge at the output capacitor C to be discharged via the internal switch, and as a result the V pin L OUT quickly returns to the V level. SS The over current protection circuit and the thermal shutdown circuit are built-in. These two protection circuits will operate when the output current reaches current limit level or the junction temperature reaches temperature detection level.
