Description
ELM99451A-S is a CMOS voltage regulator that provides a large current. It consists of various devices such as a reference voltage source, error amplifier, low resistance output transistor, short-circuit protection circuit, output voltage setting resistor, and chip-enable circuit. The output voltage is fixed internally with high accuracy. ELM99451A-S exhibits excellent characteristics, including a small input-output voltage difference due to the low resistance output transistor and high load stability due to the high gain error amplifier. It is available in two package options, SOT-89-3 and SOT-89-5, with the latter being used for the chip enable version.Specifications and features
