GENERAL DESCRIPTION

The XC6230 series are low on-resistance / low dropout voltage, highly precise, low noise, high PSRR, and large current High Speed LDO regulator IC.

Internal circuitry includes a reference voltage supply, error amplifier, driver transistor, over-current protection circuit, in-rush current prevention circuit,

reverse current protection circuit, thermal shutdown circuit, and phase compensation circuit.

A built-in 0.17Ω low ON-resistance Pch driver transistor which can output up to a maximum output current 2.0A are also enclosed in a small

surface-mount PKG, even in applications that input and output voltage difference is you use a very small state, it is possible to use in the space-saving.

The over current protection circuit will operate when the output current reaches its current limit. The thermal shutdown circuit will operate when the
