Work Principle

The BH18RB1WGUT-E2 series linear voltage regulators are current-mode, CMOS based, low drop-out voltage regulators, operating from a wide range of input voltages: 2.7 V - 6 V. They have an adjustable output voltage with an output voltage range of 0.8 V - 5.5 V. The linear voltage regulators are designed to provide very low dropout voltage, low supply current and low output noise.

The linear regulator consists of a P-channel MOSFET, a set of precision voltage reference and an error amplifier. The error amplifier compares the preset, externally adjustable output voltage to an accurate internal voltage reference, and controls the P-channel MOSFET in order to regulate the output voltage.The external resistor, R1, program the desired output voltage, while the external capacitor, C1, controls the device\'s output current and improves the line transient response. The current through the P-channel MOSFET is determined by the relationship between R1, the voltage reference and the error amplifier. The output voltage is then the voltage reference multiplied by (1+R1/R2).

The BH18RB1WGUT-E2 series have an enable pin designed to disable the regulator when the enable pin is in the low state. Additionally, the linar voltage regulator have a very low quiescent current, resulting in a power loss of only 200 µA in quiescent and dropout conditions, making this voltage regulator highly efficient.
