LP873300RHDTQ1 General Description

One standout feature of the LP873300RHDTQ1 is its automatic PWM/PFM operation, which optimizes efficiency across varying output currents. Additionally, the device supports remote voltage sensing, enabling accurate voltage regulation by compensating for IR drop between the regulator output and the point-of-load. This ensures that the output voltage remains stable and precise under different load conditions

Key Features

Four programmable output voltage levels
Low-power sleep mode with autonomous wake-up
Two precision reference voltage outputs (REFIN, REFO)
Sleep and wake control via dedicated pins
Power-good signal (PGOOD) with hysteresis
Temperature-compensated oscillator (TCO) for low jitter
