The S-812C Series from ABLIC are Positive LDO Voltage Regulators that are designed for portable device applications that require high voltage withstanding capability. They require an input voltage of up to 16 V. These LDO regulators provide an output voltage of 2.0 - 6.0 V and have a drop-out voltage of 120 mV. They include a reference voltage detector, an error amplifier, P-channel MOSFET, a parasitic diode, a phase compensation circuit, and protection circuits. The phase compensation circuit integrated into these ICs ensures high stability and uses an ON/OFF circuit to optimally control the operation. They allow the users to use a ceramic capacitor as the output capacitor to prevent ripple effects at the load.
These LDO voltage regulators are equipped with built-in short-circuit protection circuits to prevent over-voltage-related damages. They are available in surface-mount packages that measure 4.5 x 2.5 x 1.5 mm and are ideal for home electric appliances, battery-powered devices, and communication equipment applications.
