Working Principles

The MAX1792EUA15 is a linear regulator that regulates the input voltage to a fixed 1.5V output voltage. It achieves this by using a pass transistor in conjunction with feedback circuitry. The feedback pin (FB) monitors the output voltage and adjusts the pass transistor accordingly to maintain a stable output. The enable pin (EN) controls the regulator's on/off state, allowing for power management. The bypass pin (BP) provides an optional low-pass filter for noise reduction.
